When To Do Diesel Engine Overhaul

Diesel engines are robust and reliable if properly maintained. Diesel engine overhaul is part of the maintenance you can perform on your diesel truck once in a while. Performing an engine overhaul is expensive but worth taking.

What is Diesel Engine Overhaul?

An engine overhaul is when your mechanic dismantles and replaces almost every part of the engine. The aim of performing an engine overhaul is to restore its power. 

Performing an engine overhaul varies depending on each part of the engine and how much repair it needs. To perform a complete diesel engine overhaul, you must disassemble, clean, inspect, repair, and test the engine.

Signs that Your Truck Needs a Diesel Engine Overhaul

The odometer tells it when your engine requires an overhaul. You should perform an engine overhaul for your truck after covering at most 700,000 miles. Upon covering this mileage, you should change the head gasket or injectors. For a successful performance of this task, consider the services of a professional mechanic. Here are some signs that your diesel truck engine needs an engine overhaul.

Rough Idle

Your engine can be revving up and down as it struggles to balance fuel and compression. Sometimes, your truck can hesitate while idling. If this happens, the injectors might be faulty or have improper valve clearance. When you experience a rough idle, it is high time you perform an engine overhaul.

High Fuel Consumption

When your diesel truck starts to consume fuel abnormally, it indicates that it is losing power. High fuel consumption can signal issues ranging from the camshaft to dirty fuel or even faulty injectors. Increased fuel consumption clearly shows that you should perform an engine overhaul.

High Consumption of Oil & Coolant

If the rate at which your truck demands oil and coolant increases, these liquids might be leaking, the cylinder might be cracked, or the head gaskets might be faulty. If your truck is burning oil, consider checking it before it escalates to significant issues. The increased frequency at which your truck requires such liquids indicates that you should perform an engine overhaul. 

Production of blue Smoke

When blue smoke comes from the exhaust pipe of your truck, it is a clear indication of the existence of oil in the combustion chamber. The primary responsibility of oil is to lubricate the entire engine. Engine pistons depend on oil for proper functioning. Sometimes oil gets into the combustion chamber due to old piston rings or leakages. Suppose your truck produces blue smoke even after performing the basic service. It is high time to think of performing a diesel engine overhaul.

Performing Oil Analysis

Another way to determine whether your engine needs an overhaul is by analyzing oil composition. Oil analysis helps determine if unfiltered air has got into the system. To get an accurate result, consider performing regular oil analysis


When operating your diesel truck, keeping an eye on the odometer is essential. Apart from checking your odometer, pay attention to your truck. If it produces any of the above signs, consider performing a diesel engine overhaul to restore your engine’s power.

Rough Idling Causes in Trucks

Rough idling is something every truck owner will notice, and it does not need any level of experience to note your idling. Rough idling is a common problem in trucks, but determining the actual cause is difficult. 

How To Tell If Your Truck is Rough Idling

Rough idle varies. Some may be severe, and others may be mild. A shaky and bouncy sensation usually accompanies rough idle.

Sometimes, odd sounds may come from your truck, and inconsistent RPM counts. Under normal circumstances, a truck should have a smooth and consistent RPM. If your truck has an uneven RPM, it will be experiencing idling issues.

The way your truck idles tells the general health of its engine. If you note that your idling is not normal, it is better to diagnose the problem sooner before it can escalate into significant issues that can be costly to repair. Here are some of the common causes of rough idle in trucks. 

Spark Plugs

When the idle of your truck starts to be rough, another possible cause is the spark plugs. Spark plugs are part of the ignition system, and they use the electrical current from the battery through the ignition coil to ignite the oxygen and fuel mixture. 

If your plug is faulty, it can lead to inconsistent combustion in the cylinders. If the plug is badly damaged, you will realize that the engine’s running is erratic. It would help if you are keen on the sound your engine produces. 

Dirty Fuel Injector

The fuel injectors perform the role of spraying the needed quantity of fuel in the combustion chamber at the required time, and this gives the engine of your truck optimum operation. 

When the fuel injectors are clogged or dirty, your truck’s fuel economy will go down and cause a rough idle. 

Faulty Carburetor

Older trucks have a carburetor instead of fuel injectors. When the carburetor is faulty, such trucks will emit black smoke. When the carburetor works effectively, it should not produce excess black smoke. If you note the production of black smoke accompanied by rough idling, consider checking the condition of your carburetor.

Vacuum Leak

The engine has several hoses that transmit various fluids within the engine. Such hoses create a vacuum for both air and fuel. In carbureted engines, the vacuum sucks fuel into the engine. Modern trucks have a throttle whose primary role is to regulate the engine’s speed and the airflow throughout the system. 

The throttle also creates a vacuum in the intake manifold. Time and changes in the season make these hoses wear out and will lead to leakages of liquids. In case air mixes with fuel outside the combustion chamber, the mixture will lead to an engine misfire when it gets into the combustion chamber. If such happens, you will experience a rough idle, especially when your engine is at a higher RPM. 


Rough idling is something that you should take seriously. Primarily it indicates that you should fix something as soon as possible. The above are the common causes of rough idle in trucks.

Symptoms of Faulty Diesel Fuel Injector

Diesel engines depend on fuel injector to deliver fuel into the combustion chamber. It will provide the right fuel for the engine to function effectively at the right time. The combustion chamber thus receives enough diesel to cater for the production of power.

Diesel fuel injectors usually have nozzles and a body. Sometimes they crack and wear out. When they become faulty, they do not function effectively, making it difficult for the combustion chamber to receive an adequate amount of diesel. Here are some symptoms to note when your diesel fuel injector becomes faulty.

Engine Misfire

Engine misfire indicates that the combustion chamber lacks something fundamental to facilitate the combustion process. Sometimes, this thing can be there but in a limited supply. 

When your injector is faulty, it will not be able to pump an adequate amount of fuel to facilitate ignition. When ignition fails in any of the cylinders, the injector pumps a low quantity of diesel into the cylinder.

Dirty Emissions

Dirty emissions from the exhaust pipes result from a clogged diesel injector. Such emissions result from the incomplete combustion of diesel and oxygen in the combustion chamber. 

Initially, your truck will emit white smoke that pollutes the environment. As soon as you notice such emissions, it is essential to check on your diesel injectors since such emissions contaminate the environment.

Diesel Fuel Smell

When your diesel fuel injector is faulty, you will feel the smell of diesel fuel in your truck. Such a smell is an indication of leakages. A truck requires the right amount of diesel to function smoothly, and the diesel injector has to supply fuel at the right time. 

If the diesel injector is faulty, diesel may flow at the wrong time or even in excess. In such a scenario, the smell of diesel will be rampant in your truck. 

Engine Check Light

The engine check light will appear on the dashboard whenever your truck develops issues. When the light appears, it is necessary to scan the ECU error code. 

Scanning the error code will help you determine the cause of the appearance of the engine check light. The glow plug might be faulty if the engine misfires accompanying the check light. Check the condition of the glow plugs before checking the diesel fuel injector.

Reduced Fuel Economy

Your truck will consume more fuel when the diesel injector is faulty. Apart from increased fuel consumption, the performance of your truck will reduce. The efficiency of your truck will decrease, and if you delay checking the cause, it can escalate into other issues that might be costly to fix.

Hard Start

A faulty diesel fuel injector will not let your engine start. Instead, it will crank and fail to start immediately. If you experience such, consider checking the diesel fuel injectors.


A faulty diesel fuel injector can reduce the performance of your truck, increase fuel consumption and give your truck other complications. The above are the common signs you should know to help you determine if your truck has a faulty diesel injector.

Best Way Making Your Truck Last Long in Winter

How do you make your truck last long in winter? Winter temperature is usually accompanied by extreme cold, ice and snow. Cool temperatures can lower your gas mileage and also reduce the fuel energy content of the diesel your truck uses. Such changes are because most diesel manufacturers usually change the composition of diesel to make it relatively thicker and gel-like.

Winter can interfere with the performance of your truck, but there are ways of limiting the effects of winter on your diesel truck. Here are some of the tips you can rely on to make your truck endure the winter season.

Making Your Truck Last Long in Winter

Here are some of the best ways that one can make their truck last long in winter season when it is snowy and temperatures are in their extremes.

Use Additives

Diesel fuel has more energy as compared to petrol, and this is the reason why most heavy-duty trucks use diesel-powered engines. But when it is freezing, the rate at which diesel burns go down, and it also loses some energy. 

You can use additives to reduce the rate at which the extreme winter weather interferes with diesel fuel. If you add additives to your diesel, the cetane levels will decrease. Additives, on the other hand, lubricates and protect the fuel injection system.

Your Location

Your location matters a lot when it comes to ensuring your truck endures the winter season. There are areas you will never find winter diesel, especially if such regions that do not experience the acute winter season. 

If you are living in a relatively warm area and you are planning to move to a place that experiences the winter season, consider filling your tank as soon as you start experiencing the winter weather. Doing this will enable you to get the right diesel fuel that suits your truck’s current season, making your truck more fuel efficient. 

Check the Glow Plugs

Glow plugs play a vital role in starting your diesel truck. Sometimes you might experience starting difficulties. In such an event, consider checking your glow plugs. It is essential to check the condition of your glow plugs as soon as the cold temperatures start to show up.  Change the glow pugs if you realize they are becoming faulty and cannot operate efficiently during winter.

Let Your Truck Idle

Letting the truck idle can help contribute towards making your truck last long in winter. Winter season is usually accompanied by various diesel truck issues, such as difficulty starting. When your diesel engine is cold, starting it can give you a headache. 

Diesel engines are relatively different from petrol engines which rely on spark plugs to initiate combustion. For diesel engines, the combustion depends on the compression that generates adequate heat to ignite fuel.

When the temperature goes down, the entire engine will be cold. During winter, your engine will work harder to attain the minimum temperatures to ignite fuel in the combustion chamber. It is essential to leave your engine to warm up before you start driving your truck. Also, fitting the block heater ensures that the engine is warm.


Winter temperatures are challenging. Therefore, preparing your truck before and during the winter season is necessary. When the seasons start changing, it is essential to make adjustments that will let your truck cope with such changes. 

In addition to this guide, tires are necessary for making your truck last long in winter. Consider switching to winter tires. 

Truck Preparation For Spring

What are some of the tips for truck preparation for spring? Spring is when everything changes, including temperatures that can swing from balmy and frigid. It might be sunny, accompanied by a weak storm. But sometimes spring can have extreme weather changes on a single day. As the weather is beginning to warm up, it is necessary to adjust your truck. This guide will teach you some tips to consider as you prepare your truck for the spring season. 

Check the Fluid Levels

After the winter season, it is essential to check if the fluids within your truck are at the right levels. Consider checking the brake, windshield washer, transmission, coolant, and power steering levels.

Consider topping them up, flashing, or replacing them when necessary. When performing this procedure, consider using the owner’s manual for guidance. When checking the level of fluids in your truck, it is necessary to check and change the oil and the filters.

Wiper Blades

Weather changes can warp, tear or even crack your wiper blades. Damaged wiper blades cannot efficiently wipe your windscreen during the light spring showers. When the blades cannot wipe the showers from your windscreen, the visibility will not be clear, and this can be dangerous to you and other road users. 

At the beginning of spring, it is necessary to check the condition of the wiper blades and change them as soon as you realize they are faulty.


Dirt accumulation during the winter season can be dangerous to your brakes. After winter, it is essential to check your brakes, remove any accumulation of dirt on the braking system and ensure they are properly functional. Spring season needs good braking power. It is essential to check the condition of your brakes and even replace the worn-out parts.


Tires are the only part of your truck in regular contact with the road. It is essential to ensure that they are in good condition. Good tires provide proper traction and guarantee safety as you drive your truck. 

At the end of the winter weather, consider removing the winter tires and replacing them with all-season tires. Regularly check the tire pressure because weather fluctuations during spring can cause changes in tire pressure. 


Cold winters have several side effects on the chemical formation of your battery. As the weather is changing, consider testing your battery. Ensure your battery is well mounted and the connections are tight and free from rust. 

You can use a multimeter to test your battery. If the readings are below 12 voltage, consider buying a new battery. Check the levels of fluids within the battery, and if necessary, you can refill it with the necessary fluids.

Belts and Hoses

Most belts within the engine are made of rubber that can either be damaged or hardened with cold temperatures. As the weather starts to warm up, the hoses might show signs of getting damaged. Inspecting them and replacing the ones showing signs of wearing out is essential.


It is necessary to perform a thorough checkup on your truck whenever the seasons change. Variations from seasonal changes can cause damage to the above parts of your truck. 

Easily Diesel Truck Engine Cleaning Tips

Traditionally, we have heard and believed it is not necessary to clean up a diesel truck engine. But with time, there has been an increase in the knowledge of diesel engines and how to take care of them. Cleaning the diesel engine has been one of the tips many diesel owners are implementing. When you do not take care of your diesel engine, it can lead to costly repairs and replacement of parts that you can avoid. 

Some modern diesel engines come with a comprehensive guide on how you can clean them. However, if you need that knowledge, this guide will give it to you. After reading the guide, you will understand how to clean up your diesel engine.

How To Clean a Diesel Truck Engine

Cleaning a diesel engine is similar to cleaning a petrol engine and is not very complex. You can do it at home. Here are the steps you can consider following when cleaning your engine. 

  1. Remove all the debris on the surface of the engine, including those clinging to the grill and the hood. The debris is of varied sizes. Some you can remove by pulling as some you will need to wipe out using a brush.
  2. After removing all the visible debris, turn on your engine and let it warm for 10 minutes. Doing this will melt and loosen the oil on the surface of the engine.
  3. The engine is composed of very delicate parts that water can destroy. Consider protecting components such as the alternator, air intake, sensors, and power steering filler. You can cover them using plastic bags and rubber bands. You can check your owner’s manual if you need to know where these items are.
  4. Spray the degreaser on the surface of the engine, in the grill, and under the hood. For safety, spray it from the bottom, so it does not spill on you. Let the engine relax for five minutes before taking any action.
  5. After five minutes, gently scrub your engine, grill, and hood using a brush with a long handle. When doing this, focus on the areas that hide a lot of dirt and are hard to reach.
  6. When cleaning your engine, never use a low-pressure spray, but use water and gently flow it from the hose. High-pressure spray can make water access the delicate parts of the engine. 
  7. After rinsing your engine, let it dry. You can let the engine heat to dry faster, but for a cleaner and spotless dry, you can use a cotton cloth to dry your engine by hand. 

Engine Cleaning Tips

When cleaning your diesel engine, avoid using the common household degreaser as the basic ingredients used in their manufacture can damage the aluminum and the high-strength steel within the engine. The hydrogen component of household degreasers can interfere with the electrical connection of the engine. It is, therefore, essential to buy products made for engine care.


Dirt accumulation can damage the engine with time. It is, therefore, essential to clean your diesel engine regularly, especially at the end and the beginning of every season. 

Easily Choose Between Diesel and Petrol Trucks

The primary role of an engine is converting chemical energy into mechanical energy. The process involves a chain of small explosions that occurs differently depending on the engine type. Trucks generally have either diesel and petrol engines. 

In a petrol engine, the fuel mixes with the air then the pistons compress the mixture as the spark plugs spark it. On the other hand, in the diesel engine, the air gets in first and heats as compression occurs, then the diesel is introduced into the combustion chamber.

Here is an in-depth comparison between diesel and petrol trucks that will aid you in making a decision on which to buy.

Difference Between Diesel And Petrol Trucks

What really differentiates diesel and petrol engines? You will learn how these two trucks differ in cost, towing, fuel economy, maintenance cost, lifespan, and resale value.


When shopping, a diesel truck’s price is relatively higher than the petrol counterpart. If you need a truck for basic use, it is better to check the price and go for petrol-powered trucks instead of diesel-powered ones. But, if you put other factors into consideration and have the money, consider buying a diesel-powered truck.

Towing Capability

Diesel trucks produce more torque than petrol trucks. Their higher torque gives them an upper hand when it comes to towing. Consider buying a diesel truck if you want a truck mainly for towing heavy loads.

Fuel Economy

Diesel engines are generally 35% more fuel efficient than petrol engines. Diesel has more energy making it efficient under normal circumstances. When towing, diesel engines suffer a drop in MPGs, but not as petrol engines. 

Maintenance Cost

The cost of maintaining a diesel engine is relatively high compared to a petrol engine. Although if properly maintained, diesel engines last longer. The cost of maintaining an item of a diesel engine might be twice more than that of a petrol engine. 

Modern diesel trucks have a complex exhaust system that ensures their emissions are environmentally friendly. If the diesel exhaust fuel malfunctions, the owners usually part with thousands of dollars to fix the faulty DEF.

Life Span

The building of diesel engines gives them an extended lifespan. Diesel engines are heavier and sturdier to get the work done. It does not matter which type of engine you choose. Performing regular maintenance gives your truck the longer lifespan you deserve.

Resale Value

As soon as you start driving your brand-new truck from the dealership, it depreciates. Trucks are not the best investment scheme because they depreciate very fast. But, a diesel truck’s resale value is relatively high compared to the petrol counterpart.


Choosing the best truck solely depends on your needs. If you need a truck for towing, a diesel engine will give you power and reliability and serve you for many years. But if you do little towing and want to own your truck for many years, depreciation will not bother you. In this case, buying a petrol-powered truck is the best deal.

No truck can fit all your needs because truck owners use them differently. It is necessary to know why you want a truck and make the right decision when buying a truck

Diesel Truck Odors And What They Mean

Truck problems usually appear in various signs, such as reduced performance and increased fuel consumption. Apart from this, there are several signs that your truck will show. Never take for granted the odors that come from your truck. Some of the odors result from food spillage or dirt.

Sometimes, strange smells can persist even after detailing your truck. The odor might signal a serious issue worth paying attention to. Here are some common odors and what they mean if you feel them in your truck.

Moldy Smells

Mold can form in your truck. Mostly the moldy smell comes out after turning on the AC or the heating system of your truck. The odor signals the presence of mold in the air system. In such an instance, you need to consult a professional mechanic to clean and remove mold from the air system.

Rotten Eggs

The smell of rotten eggs annoys and makes the cabin an uncomfortable place to be. You will start feeling the odor as soon as you start your engine. It is an indication that your catalytic converter is faulty. 

The catalytic converter neutralizes all harmful gases before the exhaust pipe emits them into the environment. Engine or exhaust system problems are common causes of overhitting catalytic converters. As the catalytic converter is overheating or faulty, you will feel the rotten eggs smell.

Burning Smell

There are three categories of burning smells you should know. 

Burning Toast – such a smell signals an overheating insulation or short circuit. The smell indicates a problem with the electrical system of your truck.

Burning Paper – sometimes, you might experience the smell of burning paper when driving your truck. If you feel this smell when changing your gears, the clutch could be burning, and friction produces the smell of burning paper.

Burning Rubber – Rubber is the primary raw material in the manufacture of tires, and when they wear out, they will produce this smell. Apart from tires, the pulleys have rubber belts that might be rubbing against the pulleys or slipping. When this happens, you will feel the smell of burning Rubber.

Gas Fumes

When you fill-up the gas tank of your truck, it is normal to feel the smell of gas fumes in the cabin of your truck. But the smell gradually. Reduces as your truck burns fuel. But if the smell is not decreasing, but you feel it, something might be wrong with your truck. The diesel might be leaking, and in such a situation, you need to check the fuel tank it might be leaking diesel. 

Check if the fuel line has cracks that might leak fuel. Check the condition of your fuel injectors that might spill fuel in the engine.


Truck odors are unbearable and can make your trip very dull. Sometimes the odors might be normal, but if it persists and is weird, you must take your truck for a professional check-up to troubleshoot the issue. The above are some common causes of the odor within your truck.

How To Boost Diesel Trucks Horsepower & Performance

Generally, diesel trucks are known to be robust and can easily handle any work. Diesel trucks typically have higher torque than their petrol counterparts, although they might be slow on the road. But this is not the case since the current diesel trucks are mighty fast. The faster nature of diesel engines results from manufacturers’ improvements, such as the fitting of the turbo.

If you need more horsepower, you need to upgrade the performance of diesel trucks. Truck performance mainly dwells in the engine. The engine’s essential ingredients for power production are diesel and air. Providing a conducive environment for the combustion of diesel and fuel will boost your diesel truck’s horsepower and performance. Here are some tips to increase the performance and horsepower of your truck.

Modifications of Air Intake and Exhaust System

When you upgrade and modify the air intake system, more fuel-oxygen mixture will burn in the engine, increasing the horsepower. When the air intake pipe is modified and is bigger, more cool air will rush into the engine. More cool air has more oxygen, and therefore, the compression improves.

The engine will produce more exhaust fumes when more air is drawn in. Therefore, consider installing a bigger exhaust system when installing a bigger air intake system. A bigger exhaust system also helps draw out the engine’s excess heat.

Upgrading the air intake and the exhaust system helps minimize the pressure within the engine and enables your truck to produce a fascinating throaty sound. 

Upgrade the Diesel Fuel System 

After increasing and improving the airflow and the exhaust system, more air will get into the combustion chamber. You will need to increase the fuel getting into the combustion chamber. To do this, you must upgrade the fuel pump and the injectors.

The injectors that most trucks come with are meant to reduce fuel consumption. To increase horsepower and performance, you must install aftermarket high-flow fuel injectors. For improved performance, you will need to upgrade the fuel pump that can make it cope with the high fuel demand.

Upgrading your diesel fuel system will let more fuel into the combustion chamber, thereby increasing horsepower and performance.

Modifying the ECM System

The Engine Control Module controls everything in your truck, including diesel consumption. Modifying the ECM will change how diesel trucks manage the engine and the transmission system.

Modifying the ECM will mainly adjust the pressure and timing, increasing the horsepower and compression ratio and improving your transmission system.

You can Tune, remap and chip the ECM, although this is a sensitive operation that requires a specialized mechanic. It is necessary to take diesel trucks to a pro for this modification. If not, you will fail the emission test.


Diesel truck from the factory comes with features that increase the fuel economy. If you want to get maximum from your diesel truck, consider doing away with the factory air intake and exhaust system, modifying the ECM, and upgrading the fuel system. Install relatively bigger aftermarket parts that will reduce fuel economy but give your truck the maximum power. 

Reasons To Love Diesel Truck Engines

In the market, there are either diesel truck engines or petrol-powered ones. When buying, you can choose either petrol or diesel-powered engines. Sometimes deciding on the one to choose may be difficult because you will hear those owning petrol-powered engines praise their trucks equally to those owning diesel-powered engines.

In this guide, the focus will be on diesel trucks. After reading it, you can decide which truck to choose based on what you want your truck to do for you. Here are some of the reasons why you should love diesel truck engines

The Torque

Diesel trucks usually have a higher torque as compared to their petrol counterparts. The high torque is attributed to the high compression ratio. The compression ratio is between the cylinders’ minimum and maximum volume. In diesel trucks, the cylinders are larger due to longer strokes. The pistons move up and down at a larger interval volume in each cylinder. 

Torque is the measure of the force that makes an object rotate on an axis. The above-explained process enables diesel trucks to burn fuel to generate more torque transmitted to the driveshaft. Diesel trucks can tow heavy loads and economize fuel consumption.


Diesel trucks are fuel efficient because of the thicker density of diesel fuel, high compression ratio, and low rpm performance. The thicker density allows diesel trucks to produce more power by consuming less fuel. Diesel trucks are, therefore, efficient and economical when it comes to fuel consumption as compared to petrol trucks.

Long Life

Diesel engines are usually big, which is why they last longer. They have higher compression ratios and higher cylinder pressure. For this reason, they have large crankshafts and camshafts that need larger bearings with big sturdy rod bolts. 

The large crankshaft and camshafts offer increased clearance for better oil flow. Better oil flow in the engine enhances engine lubrication resulting in reduced engine wear. Better engine lubrication increases the lifespan of the engine.

The absence of a spark plug, the existence of a piston cooling jet, and the gear-driven design are some of the unique modifications that give diesel truck engines a long life span.

Gas Economy

Diesel trucks are the best when it comes to gas mileage. Gas economy is better in bigger and heavy-duty trucks. A truck with diesel engines gets 25-30% better fuel economy, making diesel pick-up trucks more cost-effective. 

The fuel economy is due to the fact diesel fuel is denser than petrol fuel. Therefore the rate at which it burns is relatively slower than petrol. For this reason, diesel trucks will consume less after running for a long time than petrol trucks. 


There are a lot of reasons to fall in love with diesel trucks. They are powerful and can endure any task. The feeling of driving a diesel truck is entirely different from petrol trucks due to the big nature of the engine. Diesel trucks are generally pocket friendly when it comes to servicing. You only need to stick to your routine service and replace worn-out parts. 

Basic Diesel Truck Maintenance And Repair Tips

Every truck owner dreams of giving their trucks a long life span of service by taking care of them and there is no better way than getting truck maintenance. Owning a diesel truck is one of the best things to happen to you. Some of the most powerful trucks are powered by diesel engines. Most diesel engines need less maintenance as compared to petrol engines. But this does not mean that servicing them is a walk in the park. Some things have to be put in place to ease the maintenance of your diesel truck.

Here are some critical diesel truck maintenance tips to keep your running smoothly.

Regular Cleaning

While using your truck, you run over all sorts of dirt, and some get into the engine. Therefore, cleaning your engine is essential and this will ensure that it serves you happily. Accumulating dirt particles in various parts of your truck can damage it. Ensure you use clean fuel to give your engine good health and smooth operations. Diesel engines are sensitive to fuel with high sulfur concentrations and can lead to expensive repairs.

Always Check the Levels of Fluids

The most important maintenance tip you should have at the figure tips is checking the fluids. Trucks use various fluids such as transmission, brake, oil, diesel, water, and engine coolant. Sometimes the engine coolant might be acidic and corrode other parts of your engine. It is essential to do a regular check on the acidity of the coolant.

Having enough coolant and oil is essential to prevent your engine from overheating. Also, check the level of other liquids and top them up when they are low.

Change the Filters

Filters are an essential part of a diesel truck that plays a vital role in your truck’s performance. It is necessary to change the filters after covering 20,000km. Modern diesel trucks have two fuel filters. During routine service, ensure all these filters are changed.

Air filters should also be checked and replaced at the appropriate time. The fuel and oil filters play the role of trapping all the impurities in the fuel and air. They thus ensure the engine receives clean fuel and air.

Change Oil

Oil changing is another tip that will leave your engine running smoothly. Diesel engines always experience harder driving and towing, which wears out oil very fast. You will need to change the oil at 8000 km as part of the regular truck maintenance. If your truck has been driven for a long, consider changing the oil whenever you change the filters. Ensure you use the right oil for your truck, and in case you need to know, you must check the user guide.

Check on the Smoke

Exhaust smoke is essential when you want to diagnose the health of your engine. Checking the exhaust system enables you to catch early developing problems. If you note the emission of strange fume, consult your mechanic, or even if a strange sound comes from the exhaust system.


Diesel trucks are mighty and reliable. But, for them to give you the service you deserve, you have to perform the basic truck maintenance as laid down in this guide.

Warning Signs Your Truck Need Maintenance And Repairs

Trucks are known to be heavy-duty vehicles with higher torque. As they serve you with time, they develop issues you should always pay attention to. You can avoid such issues at an earlier stage because the truck need maintenance and minor repairs, but if left, they escalate into major problems that become expensive to repair.

If you own a diesel truck, you must know some early warning signs that the truck need maintenance. Ignoring such signs leads to significant and expensive repairs. Here are some warning signs that your truck requires maintenance and repairs.

When the Engine Becomes Hard to Start

Diesel engines usually depend on compression to start. If your mechanic sees a problem with the system, they will usually test to see whether the problem is with the cylinder head or something like a dirty oil filter. Dirty air or oil filters interfere with the fuel and air feeding into the combustion chamber, and therefore you will experience hard starting problems.

When the Turbo Charger Starts to Fail

Turbochargers boost the engine’s power by delivering more compressed air into the combustion chamber. When your turbo is faulty, black smoke will usually come from your truck’s exhaust pipe. And also, the consumption of gas will either increase or decrease significantly. If this happens, it is necessary to take your truck for a check-up.

Blue Smoke From the Engine

Blue smoke is a clear indication that something is fishy in your engine. Usually, oil leaks into the combustion chamber, and worn-out cylinders are some of the common causes of this. When blue smoke is assumed, it can escalate into serious issues that might lead to an engine overhaul. The moment you note that the smoke from your truck has changed its color, consider taking it for a mechanical check-up as soon as possible.

Leakages of Engine Oil and Cooling System

If your engine oil starts to leak, it might end up in the cooling system and damage the radiator and another part of the engine. This could be sign that the truck need maintenance and repairs. Note that your engine oil is leaking, you will see abnormal smoke from the exhaust system, and oil stains will always be under your truck.

The cooling system is composed of liquids, which play the active role of cooling and maintaining the engine’s temperature. When they leak, the system might not function effectively, which can lead to engine overheating. Leakages of oil and liquid indicate that you should take your truck for routine service.


It is normal for the engine to heat due to friction of the moving parts and combustion. When you start driving your truck and realize it is overheating, it is essential to park by the road and turn off your engine immediately. Too much heat can damage the radiator, plastic pipes, and other vital engine parts. Overheating is an indication that your truck need maintenance.

Conclusion On Signs Your Truck Need Maintenance

Routine servicing is one of the basic maintenance tips every truck owner should consider doing. Every truck manufacturer indicates in their guide the best time for doing routine services such as oil changes, filter changes, and general engine checks. The above are some of the signs that if you see from your truck, consider taking it for service maintenance.

Preparing Your Diesel Truck For Winter

The hot temperatures are coming to an end, and winter is just starting.  If you have a diesel truck, it should serve you anytime, despite the seasonal change.  For your truck to give you better and exemplary services during winter, there is no shortcut, but you must prepare it.  Remember basic preparations such as checking the health of your battery, changing oil, adding anti-gel fuel additive to the tank, and many more.  As soon as you finish reading this guide, you will know all the preparations you need to perform for your truck as the cold weather approaches.

Check Your Batteries

The lifespan of a standard battery is between two to five years. After using your truck during summer, when liquid evaporation and corrosion are common, the cold winter kills the battery that has been weakened during summer very fast.  It is, therefore, necessary to check the health of your battery as soon as the season starts to change.

A multimeter is an essential gadget to check your battery’s health.  To use it, ensure your engine is off and connect it to the leads of your battery.  A healthy battery usually reads 12.6 voltage or more when the engine is running.  But if the multimeter readings are below 10 volts, your battery is in a critical condition, and you should change it.

Change the Fuel Filters

Most freezing in diesel trucks occurs around the fuel filters.  A very minimal amount of diesel remains in your filter when your diesel stays overnight.  Installing a new fuel filter is not an assurance that you won’t have gelling issues, but doing this will give you a fresh start.  Changing the fuel filter before winter saves you from doing the job during the cold weather.  Also, you must keep an extra fuel filter in your truck.

Use Anti-Gel Fuel Additive in Winter

Even diesel fuel blended to work better during winter can reach its limits and start to gel up when it is freezing.  There are always no standard temperatures that diesel fuel begins to gel due to the difference in the diesel quality and the degree of exposure of various trucks.  For this reason, you must use a fuel additive during winter; the best is all season or the one designed for winter.  Such additives prevent diesel from gelling up in the fuel tank.

Test the Condition of Your Block Heater

During extreme winter, block heaters are usually life savers.  The bad news is that most diesel truck owners never realize that their block heater needs to be functional.  It is easy to test if your block heater is functional.

You need to clean the prong plugs, use a multimeter set in ohms, and attach it to the plugs of the prongs.  A working block heater will read between 9 to 25 ohms.  When it is faulty, it will give readings below 9 ohms.


Winter weather usually freezes everything and might end up freezing your truck, so preparing your truck for winter is essential.  It is also necessary to do tire changes in preparation for winter.  Fix winter tires for better traction. 

Rod Knock – Top Symptoms & Causes Rod Knocking in A Truck

What is a rod knock in an engine? If you are a newbie and just getting to know some mechanical things with trucks, or vehicles in general, then this guide is for you. Nobody wishes to hear rod knock from their engines because it results in costly repairs. As you read this guide, you will know its causes and tell when your engine suffers a rod knock.

What is Rod Knock?

Rod knock is a deep sound from your truck’s engine. It results from worn-out rod-bearing. The truck’s connecting rod bearing has more clearing that causes additional movement. When your pistons change their direction, the metals start to heat, resulting in the knocking nose.

Causes of Rod Knock

Worn-out connection rods are the most common cause of rod knock. Here are some other causes of rod knock that you should know.

Worn-out Bearings

The up-and-down motion of the pistons enables the crankshaft to rotate and sends power to the wheels. The bearings ensure that the pistons move in a smooth and controlled manner. However, as time goes by, the bearing starts to wear out, and when this happens, the piston rods will rattle against the crankshaft. You will hear a rod-knocking sound.

Poor Timing 

Poor timing is another reason for the rod knock in the engine. Timing is the period when the computer controls the spark plug to fire. The spark plug is unable to fire at the required time when timing is off, leading to a series of detonations within the cylinders. If this happens, you will hear the detonation knock.

Lean Fuel Air Mixture

You will hear the rod knock when there is a lean fuel-air mixture that is usually caused by defective oxygen sensors, failing fuel injectors, and faulty fuel pumps. You will experience a lean mixture when there is less fuel and too much air in the combustion chamber, which will interfere with the proper combustion.

Faulty Knock Sensor

You will hear the detonation knock when the knock sensors malfunction. This occurs on rare occasions on newer trucks because the fuel-air ratio, fuel injectors, and timing are all computer controlled.

The knock sensor will always detect any issue and signals the ECU, and corrective action is taken immediately.

Symptoms of Rod Knock

There are two main symptoms of rod knock you should know.

Knocking Sounds

The production of a knocking sound is the primary symptom of rod knock. You will hear a loud sound when you start your truck. The sound will be louder as you press the gas pedal.

Low Oil Pressure

Your oil pressure will reduce as soon as the bearings between the piston rods and the crankshaft fail. You will notice this when you are starting your truck.

The check engine oil light will appear on the dashboard, which will notify you that the oil pressure is low. When this light appears and disappears, it strongly indicates that the bearings are completely worn out, and you should consider replacing them before the worst happens.


Rod knock sound is a serious sign you should never ignore when you hear it from your truck. The above are some of the causes and symptoms worth knowing and should help you better maintain the vehicle.

Benefits of Timely Brake Repair Tips For Your Truck

Do you know the importance of timely brake repair and maintenance? Brakes are an essential part of every truck, which enables you to control your truck while on the motion. You should ensure the brakes are functional before starting your engine.

Brakes are some of the critical parts you must service when maintaining your truck. If your brakes are faulty, your life and other road users will be at risk. For this reason, it is essential to be alert and note when your brakes need a repair service. You will enjoy some of the below benefits when you perform a timely brake repair for your truck.

Gives Your Truck a Long-Life Span

The overall life span of your truck increases when you repair your brakes in time. It is the brakes that control your truck. When they are faulty, the chances that your truck will hit the road potholes and bumps are high. Other parts, such as the shocks, will be damaged when this happens. All these reduce the lifespan of your truck.

You will have Peace of Mind

If you repair your brakes in time, you will be confident and have peace of mind knowing that you and your passengers are safe. You can comfortably take full control of your truck when in motion. You will be sure of reduced braking distance since the brakes will engage as soon as you apply them.

You Will be Safe on the Road

Effective brakes prevent road accidents by enabling you to stop your truck when needed. Bad brakes cause brake fade, brake fluid leaks, and brake failure. All these problems can lead to a longer stopping distance.

An increase in the stopping distance increases the chances of your truck causing an accident.

Increases Fuel Economy

Properly functioning brakes will slow down your truck efficiently, saving you money at the fuel station.

Your truck will require a lot of pressure to stop if your brakes are old, reducing fuel economy. Brake repairs will let you get the most from your truck regarding usage and general performance.

Saves You From Costly Brake Repair

When you repair your brakes in time, you will not have to do major repairs in the future. But if you take the time to repair your brakes, the entire braking system might be damaged which will be expensive to fix. Apart from needing to fix the entire braking system, other parts such as shocks, the suspension system and the entire body of your truck might suffer. Fixing all these will be costly. 


Usually, the braking system plays a vital role in your truck. Besides bringing your truck to a halt, braking systems are essential in controlling road accidents. The system is composed of several parts that work together. The brake pads are the ones that play a significant role in controlling the speed as well bring your truck to a halt. Their role and location expose them to a lot of friction, and the materials they are made of wear out every time.

After attaining a specific mileage, it is necessary to replace the brake pads. If you ignore replacing them, they might damage the brake rotors or even the entire braking system.

Steps to Remove Stuck Lug Nut On Truck Wheels

A stuck lug nut can be hard to crack, requiring a lot of keenness so as not to damage your rims. After reading this guide, you will know how to remove stuck lug nuts safely as part of your routine truck maintenance.

Lug nuts become stripped due to various reasons. When they are corroded and rusty, when you use the wrong socket and incorrect torque, and when trying to remove your wheel, you will realize that one or more lug nuts are stripped. If this happens, consider performing the below procedure.

Use an Extractor Socket, Breaker Bar, or Hammer

Using these tools is the best method, with an accuracy rate of 99%. Such tools are readily available in your garage. You will need a breaker bar, penetrating oil, a hammer, and a socket. Before performing this procedure, ensure your truck is parked on a flat surface. You can also use the wheel chocks if you engage the emergency brakes.

Use penetrating oil to soak the stuck lug nut, which will do away with rust covering it. After soaking it, fix the long socket and hit it using a hammer. Be cautious when doing this so that you do not hit your fingers.

After hitting severally, you can remove the socket, insert a sizable nut extractor, and hit it with a hammer.

At this point, the lug nut has started to soften. Attach your breaker bar and use a little force to remove it. 

Use a Blowtorch

Using a blowtorch is the fastest process, but not everyone has it. If you have it, you will need a wheel spanner or plier, which will help you to grab the lug nut after getting hot. When using a blowtorch, do not use oil because it might cause a fire.

Use your blowtorch to heat the nut, be cautious and heat the lug nut slowly. After it has got adequate heat, you can leave it to cool down. Repeat this until your lug nut becomes loose. The secret behind this procedure is that the wheel nut expands as it becomes hot, making it easy to remove the stuck lug nut.

Use a Grinder/Wrench

Here you will also need a penetrating oil. Never forget to let it soak to remove the rust surrounding it.

Use your grinder to make edges around the nut, enabling you to grab it with your wrench. After getting a good grip on it, use a wrench to turn it until it becomes loose.

Use a Screwdriver, Chisel, or Hammer

When all the above procedures have failed, consider doing this. First, apply penetrating oil around the stuck lug nut and give it time to soak. 

Use your chisel to push the screwdriver into the nut. Doing this will create a notch on the surface. Wedge your screwdriver into the notch and tap it using a hammer in a counterclockwise direction. Do this until the lug nut breaks loose.


Removing a stuck lug nut can be hectic, but with adequate knowledge provided in this guide, you can do it using some tools that are locally available in your garage. 

When Should You Replace Shock Absorbers of Your Truck

Do you ever replace shock absorbers in your truck? The shock absorber plays the role of ensuring that the wheels of your truck are in complete contact with the road. They also control the movement of the springs and suspension to offer you a smooth ride. The shock absorbers never take the entire weight of your truck. Instead, they will take the kinetic energy generated as the suspension moves and changes it into thermal energy. 

When driving under normal conditions, your shock absorbers will serve you for 50,000 miles. It is necessary to replace shock absorbers as soon as they show signs. 

Symptoms of a Bad Shock Absorber


The shock absorbers have valves or seals that usually wear out, and if this happens, the fluids will flow past the valves. On such an occasion, your truck will vibrate when driving.

Truck Swerving When Braking

Your truck will likely develop handling issues as the fluid flows past the seals, leading to monumental movement within the cylinder. The weight of your truck might be challenging to manage when trying to make a turn. In addition, when you apply brakes, your truck might stop further than expected.

Uneven Tire Wear

When your shocks are worn out, keeping your truck on the road becomes hard. Your truck will bounce whenever it comes into contact with an imperfect surface. An area of your tire will have typical wear, but the rest of the tire will not. It is referred to as uneven tire tread, which escalates to further handling issues. Replacing a tire with this problem will not offer a permanent solution, but check and replace shock absorbers

Increased Stopping Distance

When your shock absorbers are faulty, your truck will take time to stop when you press the brake pedals. An increased stopping distance of 20% can make a big difference when trying to avoid an accident.

Whenever you realize that your truck takes time to stop when your press the brakes, it is due to faulty shock absorbers.

Cracked Bushings

Sometimes it is necessary to perform a visual inspection on your truck and check the condition of your shock absorbers. Each shock has ends where they bolt to your truck. There are rubber bushings at these ends. The rubber bushings usually crack when the shock absorbers are faulty. When this happens, your truck will produce noise as you run over a bumpy road.

Fluid Leakages

Sometimes the seals around the shock shaft develop leakages. In such a scenario, you will see fluid running on the body of your shock absorber to the pavement. Whenever the fluids leak, the performance of your shock absorbers reduces, and they will never function normally. When this happens, you will experience handling difficulties as you drive your truck. 


The cost needed to replace shock absorbers varies depending on the model of your truck and the labor cost. It is necessary to know the signs of a damaged shock absorber so you can tell when to replace them.

4 Symptoms of Bad Alternator System in a Truck

In this guide, we will look at how to know when you have a bad alternator in your truck. The electrical system is an integral part of your truck, which is the source of entertainment, gives you vision at night, and enables you to signal other road users. The electric system will allow your wipers to work effectively in heavy rain. There must be a power source for all these electric parts to function effectively. The alternator is the primary power producer of any truck. As the name suggests, it changes the energy from the engine to that which can be utilized by the electrical parts of your truck.

The alternator plays the role of charging the battery of your truck, and it is connected to the battery, so the battery does not run out of power. The work the alternator does stresses it, and at some point, it breaks down. This guide will focus on some symptoms that will let you know if your alternator is faulty.

4 Symptoms of a Bad Alternator

The battery warning check light on the dashboard is the most common symptom of a bad alternator, sometimes your headlight will not be stable when put on. You may also hear a funny noise from the engine. Now you know the most common signs, having an in-depth look at them will cause you no harm.

Battery Warning Light

The appearance of a battery warning light on your dashboard clearly indicates that your alternator is faulty. How will the appearance of the battery check tell you that your alternator is defective? When your ignition is on, your battery’s voltage is over 13 volts. A healthy truck battery has 12 volts, which will shoot to 14.2 when the alternator charges it. When the voltage drops to 13 volts and the ignition is on, the battery check light will appear on your dashboard.

Dim Headlight

The headlights consume a lot of power, and thus they need a lot of electricity. When they receive adequate power, they will be very bright. As your truck runs, the headlights will consume the light on the alternator. A faulty alternator will not supply adequate power to the headlights, making them not light bright.

Battery Starts to Drain Faster

You will be charging your battery regularly, but it keeps draining even if it is still healthy. When you note this, the alternator could be faulty. A faulty alternator will supply the battery with inadequate power, and other electric parts of the truck will depend on the power from the storm, which will drain it very fast.

Funny Noise from the Engine

The alternator has bearings and spinning components that are metallic. If it experiences any physical damage, your truck will produce a loud squealing or banging nose. Faulty bearings mainly cause noise in the generator. You can easily spot your truck’s alternator from the engine bay, so you can easily open it and check the cause of the noise. This is one way of knowing whether you have a bad alternator.


The above four are some common symptoms of a bad alternator, knowing them quickly lets you know the right area to check if you experience any of these signs. This is something that most people do not keep in mind when doing regular truck maintenance.

What Causes Oil On Spark Plugs In My Truck Engine

Have you ever asked yourself what causes oil on spark plugs in a vehicle? If you have, then this guide will detail all you need to know about that. The ignition system has various components that work together to initiate combustion in the engine. Any faults or irregularities in the spark plug could cause problems in the ignition system. For a spark plug to function effectively, it has to be in a conducive environment. 

The engine has three vital liquids, oil, water, and fuel, and such liquids should not mix. If they end up mixing, your truck’s engine will likely break down or experience technical problems.

What Causes Oil On Spark Plugs

Oil is an important component of your engine. It lubricates and helps the moving parts run smoothly. When you see oil on spark plugs, it indicates oil in the combustion chamber, which might not be the best indication for your truck. Here are some of the common causes of oil on the spark plug.

Leakages on the Valve Gasket

The engine has a valve cover that fills the wells, and the spark plug has O-rings around its holes. These holes can be external or integrated with the valve gasket. Heat destroys the valve gasket, if this happens, the oil will leak into the spark plug holes. 

When your truck fails to start, check the condition of the spark plug. If you find the whole of it has oil, consider replacing the valve cover gasket and the O-rings around your spark plug.

Faulty Crankcase Ventilation

The oil at the tip of your spark plug indicates that it is coming from the combustion chamber. The existence of oil in the combustion chamber should worry you because it is a bad sign. When you have faulty crankcase ventilation, the oil will find its way into the combustion chamber and the tip of your spark plug.

The blockage on the crankcase ventilation creates a lot of pressure, leading to oil being forced into the combustion chamber. 

Faulty Turbocharger

You will observe oil on your spark plug when your turbocharger is faulty. If oil leaks from the turbo inlet compressor sealing, it will pass through the combustion chamber to the spark plug. If such happens to your truck, check the crankcase ventilation. Sometimes the intercooler and intake pipes can be filled with oil, damaging your turbocharger.

Damaged Valve Seals

The valves regulate the flow of air and fuel into the combustion chamber and allow the exhaust gases out of the combustion chamber. The valves close after adequate air and fuel have entered the chamber for all the activities to occur in the combustion chamber. The outlet valve will open to eliminate the exhaust gases from the combustion chamber. 

When the valves are faulty, the oil will quickly get into the combustion chamber. Once the oil is in the combustion chamber, it will quickly find its way into the spark plug.

Damaged Pistons

You are likely to notice oil on spark plugs when the pistons are faulty. The high speed at which the pistons operates exposes them to tear and wear.


The presence of oil on spark plugs should not be treated lightly because it will not enable your spark plugs to initiate combustion and the starting of the engine. Knowing the common causes of oil in the spark plug will aid you in checking specific engine parts to determine the cause.

Best Way To Get Truck Battery to Last Longer

If you are looking for a way to get truck battery to last longer, then this guide is for you. It becomes stressful when the battery of your truck goes flat abruptly. Several factors, like harsh weather conditions and how you use your truck, can affect the lifespan of your battery. You can prevent your battery from running flat. An average truck battery should last between three to five years of service. To avoid changing your battery every one or two years, check this guide and practice these simple methods.

How to Get Truck Battery to Last Longer

Here are some of the best-proven ways that you can be sure to get truck battery to last longer.

Always Test the voltage of Your Battery

A regular check on the voltage of your battery will save you from battery failure when on the road. Professional mechanics does battery checks, but there is a device you can use to check the voltage of your battery at home. 

A voltmeter is a device you can use to check the voltage of your battery at home. The digital voltmeters give very accurate readings. For good records, consider testing the voltage of your battery when your truck has been turned off for 12 hours.

To use a voltmeter, connect the positive lead to the positive terminal of your battery, then connect the negatives. After connection, the voltmeter will be able to read. The readings will be 12.4 and 12.8 volts when your battery is fully charged. If the readings are way below 12, consider calling a professional to inspect your battery.

Your Truck Should Not Spend Much Time Parked

The battery will not have time to charge when your truck spends more time in the parking lot. The battery will perform optimally when your truck is driven more regularly. It is necessary to take your truck out for a drive for not less than 30 minutes to warm up the engine and circulate the fluids.

If your truck sits for weeks, your battery will need attention when you want to use it. Always ensure it has a full charge and the level of electrolytes is correct.

Clean Your Battery Regularly

Dirt, dampness, and grime can cause leakages on the battery, which might lead to short-circuit. You can use a sponge to remove the grime and other impurities on the surface of your battery. 

The battery terminals and the clamps are prone to corrosion. Corrosion on such surfaces hinders current circulation. To give your battery a longer life, consider cleaning it to remove such impurities. When your truck is being serviced, you can tell your mechanic to clean the battery for you.

Never Use Electronic Accessories When the Engine is Off

Keeping the lighting system on or using the infotainment when your engine is off can drain your battery. When the engine is off, the alternator is not working, and the electrical system will drain power from the battery. 

Always check to ensure that all the electric components are off before leaving your truck. When leaving your truck, ensure it is locked. Doing this is for safety purposes, and also it will close the computerized system of your truck.


The battery should give you full service, but its lifespan varies depending on how you use your truck. After reading this guide, you will be able to know how get truck battery to last longer. Some of these pointers should be adhered to just the way you do your regular truck maintenance.

5 Things that Destroy Your Truck

In this guide, we will be covering some of the things that destroy your truck with the help of guiding you on how to get it to last longer. Your truck will start getting damaged the moment you take it from the showroom and drive it, and some habits like careless driving accelerate damage to your truck. Such practices expose you to high bills when you take your truck for repairs. Most drivers shorten the life span of their trucks deliberately. This guide will show you some things that destroy your truck yet you may not know.

5 Things that Destroy Your Truck

Here are some of the crucial things that you need to keep in mind to ensure that your truck will last longer.

Skipping Oil Change

Engine oil serves the purpose of protecting your engine. It cools, lubricates, and cleans the engine. As it performs these roles, it will become dirty and fail to be effective. The oil filter ensures that clean oil goes to the engine by trapping particles that might contaminate the engine. The filter gets clogged with time, making it impossible for oil to pass. It is important to do an oil change regularly.

A clogged filter triggers the bypass to protect the engine from starving. When the bypass valve is activated, the engine will receive unfiltered oil, which can cause severe damage to it. Your truck might start to burn oil as soon as its engine starts to become old. This will require you to check oil levels more often.

Driving on Low Gas Tank

Regular driving when your fuel tank is low can cause long-term damage to your truck. The sediments will start to accumulate in your tank with time. If your gas level does not go too low, this is fine. But when you drive on an empty gas tank, the fuel will be drained from the bottom of your tank, and the fuel pump may pick these harmful sediments that might be trapped along the fuel system or even the engine. The accumulation of deposits can damage your engine and the fuel system.

Rapid braking and Acceleration

Rapid acceleration and braking push your truck to its limits, damaging the drivetrain. Sudden braking wears out the brake pads, and they overheat, reducing their effectiveness.

Aggressive driving interferes with brake rotors, and wheel bearings, the turbo will start making noise, and your transmission system will also slip. All these lead to hefty bills when you take your truck for repairs.

Not Using Parking Brakes

The parking brake is also called the emergency brake, and most truck owners associate it with manual transmission. If your truck is automatic transmission and you put it into parking, a lock feature called parking pawl will be engaged. Parking without an engaging parking brake makes the weight of your truck rest on a single piece of the transmission system. The parking brake will engage the braking system to hold the entire truck.

Ignoring Various Warnings

When crucial parts of your truck start to wear out, there are warnings and signs that you will feel as you drive. Assuming these warnings cause further damage, which becomes costly to repair or can sometimes lead to an engine overhaul.


The lifespan of your truck depends on how you use and take care of it. If you are a little bit careless, you will spend more money repairing it, or even it might end up being rendered unroadworthy. 

Signs Of Broken Coil Springs in Your Truck

Do you know what signs to look for when you have broken coil springs? A truck’s suspension has various parts that enable it to work efficiently. The coil spring is one of the essential parts of the suspension system. Their primary role is to absorb shock, and you will have a smooth ride when your truck’s suspension system can adequately absorb shock.

Signs Of Broken Coil Springs in Your Truck

The coil spring and leaf springs have similar roles. They both offer a riding height, which is why you will find both in most trucks. The coil springs are made of round metallic wires, wound into a helix shape having gaps between each other. The coil springs convert the motion of torque to elastic potential energy, which will provide support again. Their role exposes them to a lot of stress which wears them out with time. Here are some of the signs of broken coil springs.

Noise When Turning the Steering

When the coil spring of your truck is broken or is getting into contact with the body of your truck, you will hear a noise when turning the steering wheel. Sometimes, the spring can lay against the chassis instead of the top mount bearing. If such happens, you will experience a high bouncing noise when turning.

Rattling Noise

When the coil springs are broken, you will experience unusual noises, which increase the more you ignore them. The noise becomes worse when you accelerate or drive on rough terrain.

Uneven Tire Wear

The suspension system plays the role of balancing your wheels and tires as you drive your truck. Your tires should receive an equal amount of wear as they rotate. Your truck’s alignment changes as the coil springs start to wear out. If this happens, you will realize that your tire treads have premature wearing, which can cause severe handling issues. Your tires can blow out if you never inspect them regularly. 

Too Much Bounce

The coil springs prevent your truck from excessive bouncing whenever you hit a bump. When the springs are broken, they will not be able to prevent bounciness from happening. Your truck will be shaky when driving, which might be worse when driving on a dusty road or uneven terrain. Controlling your truck will not be easy if the bounciness becomes too much.

Sagging Corner

If your coil spring is broken, the corner it stands at will start sagging. It is easy to observe one of the corners of your truck is sitting lower than the others. The stability of your truck will be affected by the sagging. It will lead to other symptoms, such as uneven tire wear and noises.


A good coil spring will give your truck stability and a smooth ride. Several factors, such as poor driving and regular driving on rough surfaces, can break your coil springs. When they are broken, your truck will not drive smoothly the way it used to. The above are some signs your truck will have when they have broken coil springs and need some replacement or maintenance. Driving with broken coil springs is risky to you and other road users. If you realize they are faulty, consider replacing them as soon as possible.

Top Truck Tune-Up Checklist

What are some of the crucial truck tune-up checklist that you always adhere to? Tune-up simply means an overall tweak which includes the truck’s ignition system, breaker points, and condenser are replaced or adjusted. The new distributor cap, rotor, and spark plugs are installed. The ignition timing is set, and the carburetor of your truck is adjusted. The term tuned thus means optimal performance. This guide will let you know what truck tuning consists entails.

Top Truck Tune-Up Checklist

Here are some of the top truck tune-up checklist that you should always keep in mind for the best results.

Replace the Essential Components of the Ignition System

The ignition system has various parts such as spark plugs, plug wires, coil, and electrical components, which ignites the mixture of air and fuel in the combustion chamber.

The Spark Plugs

It has an electrode that wears out due to high heat and electrode arc. You will realize your spark plug is worn out when your engine misfires.

If you want to replace your spark plugs, buy the plugs of the original equipment. To do this, check the manufacturer’s manual for guidance.

Ignition Wires

The ignition wires of your truck will break with time and stop functioning. Consider replacing your ignition wires if your truck starts rough idle, misfires, or has a dead cylinder.

If replacing the ignition wire, transfer one wire at a time from the old to the new cap. 

The Ignition Coils

The coils do the role of transforming the low battery voltage into thousands of volts. The coils will wear out as they receive high voltage electricity.

If you hear engine misfire, weak acceleration, or rough idle, conclude that your coils are worn out.

Leave Your Engine Run Clean with New Filter

A truck has various filters, such as oil, air, fuel, and cabin air filters. The filters prevent contaminants from reaching various parts of the engine and the truck. For instance, an air filter collects debris and prevents them from entering the combustion chamber. When the filters are new and clean, the performance and efficiency of your truck will increase.

Keep the Auxiliary System in Check with New Hoses and Belts

The engine has various pulleys, and the belts connect them to transfer the rotating power of the crankshaft pulley to parts such as the alternator, water pump, and other systems. The hoses transfer vital fluids, such as the coolant, throughout the engine. The belts and horses wear out as they function. Heat, cold, and daily driving habits are some of the common reasons why they wear out. When tuning your truck, consider changing all the belts and hoses.

Use the Right Fluid to Maintain Your Truck

Your truck needs various fluids to function normally. Some necessary fluids are the engine oil, coolant, brake fluid, transmission fluid, and power steering fluid. When these fluids are contaminated, the internal components can wear out quickly. Servicing these fluids can save you money before any expensive damage happens. Perform a regular inspection and change of these fluids.


The main aim of tuning your truck is to boost or maintain its performance. This guide has highlighted the vital truck tune-up checklist considerations that you need to adhere to.

Testing Condition of Engine Head Gasket For Efficiency

A blown engine head gasket is among the problems that one is likely to experience while using their truck. But there are a few more serious problems. Such issues are costly and take time to diagnose. So how will you be if there is a problem with your engine head gasket? This guide equips you with all the requirements to test for a blown head gasket.

Roles of Engine Head Gasket

The head gasket is located between your engine and the combustion chamber, and its primary role is to keep all the engine fluids in their correct channels. The head gasket’s job might sound simple but wait until it malfunctions. The head gasket near the combustion chamber is exposed to server forces and movements.

If its seals start to malfunction, your truck will run into various problems which can seriously damage your engine. 

Testing Your Head Gasket

The two most straightforward ways of testing your gasket are checking your oil and your truck’s exhaust. But, you can do a lot to try for your gasket. Here are some practical ways of testing for a blown head gasket 

Checking the Engine Oil

Looking at your engine is the simplest way of testing if your head gasket is blown. You will do this by pulling the dipstick and observing it. If your engine oil is low, you must drain it on a pan and watch it.

If it is milky instead of its original color, know it is mixed with coolant.

Checking Your Exhaust

If you realize your truck emits more smoke than usual, it might mean your head gasket is blown. When diagnosing excess exhaust smoke, you should know a few things.

First, your truck will produce more smoke when it is cold than when it is warmer, which is very typical.

Second, a blown engine head gasket produces a lot of white smoke, the color your coolant will produce if it burns in the combustion chamber.

Finally, the smoke should be excessive to determine if the problem is related to the head gasket.

Checking Spark Plugs

You will know you have a blown head gasket when you check your spark plug and notice its oil. Oil will get into the combustion as soon as your head gasket blows, and some will be on your spark plugs.

To know this, pull out your spark plug and keenly look at it.

Checking the Radiator

Checking your radiator will let you look for a few various things.

First, a blown engine head gasket will enable air into the cooling system, and your radiator will have a foamy mixture.

Sometimes, oil and fuel might mix in the system, and if this happens, you will notice a milky color in your radiator.


The head gasket gives a crucial function in your truck. If it blows off or gets damaged, your truck will not be able to serve you. Immediately when it gets damaged, you notice be keenly observing your engine. This guide has given you the most basic and common ways of testing if your head gasket is faulty.

When To Replace The Thermostat of Your Truck

Do you know when you need to replace the thermostat in your vehicle? If not, then this guide will take you through when you should do it. Several activities take place in the engine, which generates a lot of heat. Too much heat from the engine is dangerous as it can melt down the plastic hoses and seals. Apart from that, the engine itself can break down. The engine has a cooling system that ensures it works at its optimal temperature. 

What is a Thermostat?

The cooling system is a vital part of your truck, and it comprises various components such as the radiator, coolant, and thermostat. What is a thermostat? For the cooling system to function effectively, it has to have what triggers it. A thermostat is a temperature-sensing device within your engine. It opens and closes automatically to regulate the temperature of the engine. 

The thermostat closes when the coolant has just been released into the engine. When the coolant in the engine reaches a specific temperature, it will open to allow the hot coolant to flow into the radiator. The role played by the thermostat exposes it to wear. It is necessary to know the appropriate time to replace the thermostat. 

Signs that You Need To Replace The Thermostat

Your truck will exhibit some signs when your thermostat is worn out and faulty. Knowing such signs will aid you in determining when to replace them.

High Temperature

High truck temperature is the first sign that you need a new thermostat. The temperature of your truck can increase when the coolant level has gone down. But if you have just refilled your coolant and this persists. Consider checking your thermostat.

To determine that high temperatures result from a faulty thermostat, look for a spike in temperature. For example, your thermostat may be defective if your truck’s and engine’s temperature is cool but spikes very high within a short time.

Cold Engine

Mostly, people associate a hot engine with a faulty faulty thermostat, but when your engine is too cold, it is another sign that your thermostat is defective. A cold engine is dangerous and interferes with the operation of your truck.

The prominent role of a thermostat is to let the coolant move to the radiator. When the thermostat remains open, the coolant will keep flowing regardless of your engine’s temperature. It will make your engine cold and bring mechanical problems to your truck.

Problems with the Temperature Gauge

The easiest way of accessing your thermostat is by checking the temperature gauge. You must have needle nose pliers to remove your thermostat.

After removing your thermostat, consider cleaning it and placing it in hot water. Before doing this, consider checking the temperature of the water. Check the temperature gauge when the thermostat is in hot water. If it does not spike, then your thermostat is faulty.


Shared in this guide are some of the things to watch out for to determine whether you need to replace the thermostat. Between your engine and the coolant, there is a thermostat whose primary responsibility is to ensure that the coolant flows in and from the engine when necessary. When it becomes faulty, your engine will either overheat or become cold. Knowing the signs of a faulty thermostat will enable you to determine when you need to replace the thermostat.

How To Know You Have Bad Piston Rings in Your Truck

How do you know that you have bad piston rings in your truck? The internal combustion engine has cylinders. The cylinders are the powerhouse of your engine. Inside the cylinders, there are pistons that have rings around them. The rings’ primary function is to help keep the combustion chamber pressurized, making it easy for combustion.

How To Know You Have Bad Piston Rings

The piston rings are the primary seal between the piston and the walls of the cylinder. If the rings wear out or fail, you will experience your engine becoming less powerful, together with other problems. This guide will focus on the common signs your truck will give when it has bad piston rings.

Emission of Blue Smoke

When your piston rings are worn out, your truck will start to emit blue smoke. The blue smoke results from oil getting into the combustion chamber and mixing with fuel and air. This mixture produces a blue smoke when burning. When you see blue smoke, consider consulting your mechanic as soon as possible. If you ignore these warnings, your truck will develop other serious problems that might be costly.

Weak Acceleration

The combustion chamber loses pressure when the piston rings are damaged. Less pressure in the combustion chamber will lead to poor acceleration as your engine will lose power since the pistons cannot effectively compress the air-fuel mixture.

When you press the accelerator pedal against the floor, but your engine is still not giving you adequate power, consider checking and replacing your piston rings. Doing this will restore the compression pressure.

Oil Leakages

High pressure develops inside the crankcase and interferes with the sealings of the engine. Poor sealing makes oil leak. When you experience many leaks, consider checking the pressure in the crankcase of your truck.

To check the crankcase pressure, leave your engine idle as you carefully open the oil cap. You should not experience any pressure while doing this, but your piston rings might be faulty if the oil cap flies away with smoke pouring out.

Oil Disappearance in Large Quantities

When your piston rings are faulty, they will not stop oil from leaking into the cylinder. When oil leaks into your combustion chamber, the chances of it mixing with fuel and air are very high.

Your oil will leak into the combustion chamber gradually, which will make you experience a drastic drop in the oil level in your truck. Drastic drops in oil levels will compel you to refill it regularly. 

If you were used to changing the oil after every 5000 miles, you might find yourself doing it at 3000 miles. When you experience such an event, stop wasting your time and book an appointment with your mechanic as soon as possible. A professional mechanic will take time to diagnose your valve seals and piston rings and give necessary advice according to their findings.


The piston rings provide sealing for the piston. Good sealing prevents oil from getting into the cylinders and also offers the needed pressure within the cylinder. When your truck has bad piston rings, it cannot function effectively and needs to be tended to.

How To Diagnose the Ignition System of a Truck Easily

Do you want to learn how to diagnose the ignition system of a truck? The ignition system is the part of your truck that you should inspect whenever you perform general truck maintenance. Checking it does not consume much time and saves you from frequent breakdowns. 

How To Diagnose the Ignition System of a Truck

This guide will detail how to diagnose the ignition system of a truck, which is otherwise similar in many other vehicles.

The ignition has low-tension connections. Consider checking if they are tight and are not corroded. You should also check if all the low-tension wires are well insulated and if no cracks have formed on them.

Check The Leads

Check if the leads are clean, dry, and crack-free. If your truck has special guide clips, check if the leads are running inside them. The clips play the role of protecting the leads.

If the leads are dirty, use a soft cloth to clean them. If they are not in good working condition, consider replacing them. It would help if you replaced the high-tension leads every three years. Doing this will help in maintaining the peak performance of your truck.

Check if the spark plugs are well fixed on the leads and if the leads are well connected to the distributor. When doing this, have sticky tape to make tagging, so you do not mix up the connections.

The threaded collars are used in screwing the leads vertically into the distributor and are held by crimped terminals or tiny screws.

Check if there are cracks on the distributor and the plug caps. You will have to pull off the plug caps one after another to do this. Pulling one after another will protect the lead from damage. Wipe the tops of the porcelain plugs.

Remove The Distributor Cap

It may have spring clips or two small screws. When removing the distributor cap, do not drop the spring clips or the screws. Inspect if there is any crack inside the cap. Check if the sprung carbon brush at the top can slide freely up and down. There is a spring contact on top of the rotor arm. Check if this spring is free from damage or wear. You might find the roto-arm tip dirty. All you need to do is to lift off the arm and clean it by scraping. Scrapping will also remove corrosion around the rotor-arm tip.

Narrow pipes run from the distributor to the inlet manifold. If you have an older truck, these pipes will be metallic. Most of these pipes are plastic which is a push-on fit. Inspect and check the physical conditions of these pipes.

Check the Coil

The standard type has a thick HT lead flanked by two smaller LT leads. Check if the lead is correctly fixed to the coil and distributor, and ensure that the rubber seals are well fixed. Ensure that the coil is fixed adequately on its mountings.

You will see two leads from the switch to the coil, one going through the resistor while the other bypasses the resistor and provides an additional ignition strength. 


The ignition system has various parts. To diagnose the ignition system, it requires one to have prior mechanical mastry. If you haven’t done it before, consider the services of your mechanic. 

How to Troubleshoot The Starter Circuit of a Truck

In this guide, you will learn how to troubleshoot the starter circuit of a truck. The starter system is simple, and troubleshooting is not complex. All you need are a few tools like the voltmeter, test lamp, tester, and a spanner to check the starter pinion is jammed in mesh with the engine flywheel. As you read this guide, you will understand how to troubleshoot the starter system of your truck.

How to Troubleshoot The Starter Circuit

If you would like to know how to troubleshoot the starter circuit of a vehicle, then the pointers below will help you through that.

Checking the Starter Pinion

You need to switch on your headlights and try the starter. If your headlight is dim, the starter is jammed in the mesh with the flywheel. Check if there is a square stub on the end of the starter-motor spindle. If you see it, use a spanner to turn it, and the pinion will be freed. 

Before you start working on the starter, ensure the pinion is freed. If you haven’t seen the square stub and your truck is a manual transmission, consider putting the gear level in the second gear with the ignition off, release your handbrake and rock your truck forward and back until you feel the pinion frees itself. For automatic transmission, you will have to take the motor off. When the headlights are still dim, consider checking for electrical faults.

Checking for Electrical Faults

When checking for electrical faults, consider checking the entire battery. Use a tester to confirm if the current reaches the solenoid.

Testing Power output

Connect the tester between the solenoid and the output terminal to check for the solenoid tester current. Connect one lead to the battery side of your solenoid and earth and the other to bare metal on the body of your truck. If the lamp lights, the solenoid, or the starter is the issue.

Sometimes the lamp may light when you earth it to the body, but not the engine of your truck, in such a case, the engine strap might be faulty. The connection between the solenoid and the battery might be defective if the lamp does not light.

Checking the Solenoid

You need a helper who will operate the starter switch as you listen to the solenoid to check if it is working. If your solenoid works, you will feel it producing a clicking sound. The ignition switch or its terminals might be faulty if it does not work.

To know if your solenoid is delivering power to the starter motor, consider connecting the test lamp between the output terminal and the earth, specifically the battery earth terminal. If your starter switch is working, you should be able to see the lamp lighting. 

Sometimes your lamp might fail to work. In such a scenario, put your truck in neutral gear, put off the ignition, and try to bridge the two terminals of the solenoid.

Checking the Battery

Connect the voltmeter on both the battery terminals and the readings should be 12 volts or more. As the voltmeter is connected, turn on the starter switch the voltage should drop to 10.5. If the voltage does not fall, there is a problem with the ignition switch or the solenoid.


Having gone through this guide, we now hope that you know how to troubleshoot the starter. If you are unsure what to do, consider getting some expert help from your mechanic.

How to Deal with a Clogged Diesel Particulate Filter of a Truck

Diesel-powered truck owners usually ask if it is possible to clean the diesel particulate filter on their own. Diesel particulate filters get clogged. When it happens, you should not worry because there is a way of cleaning it. All you will have to do is to dive the DPF clean. Your truck will do this automatically on a long drive, but most trucks will need a little help. This guide will inform you how to clean the diesel particulate filter if it gets clogged.

How Diesel Particulate Filter Works in a Truck

To understand the diesel particulate filter, we first have to look at the functions of the DPF. The diesel particulate is in the exhaust o your truck, and it does the role of collecting soot particles from the exhaust fume so that they do not pollute the environment. 

The filter collects fine soot temporarily. When driving after covering 1000 km, the filter becomes filled up with foot, which you must remove. To remove them, you have to regenerate your particulate filter.

How to Know When Your Diesel Particulate Filter is Clogged

Several factors will let you know that your diesel particulate filter is clogged. The most common scenario is when you see the filter malfunction light showing on your dashboard. The appearance of this light is a warning that your DPF is clogged. If your truck has no particulate filter light, the engine management light will show you that the DPF is clogged.

You will feel your truck is driving differently when the DPF is clogged. For example, your truck might shutter, or the rate at which it consumes fuel will go up.

Cleaning a Diesel Particulate Filter

Prevention will supersede cure, but sometimes it might be too late for prevention. If this happens, you must look for ways of cleaning your DPF. Cleaning will always be cheaper than replacement. There are two methods of cleaning your DPF. You can do it yourself, or you can seek the services of a professional, which might be costly.

Lindemann’s total care diesel cleans the DPF by lowering the combustion temperature of soot which makes it easy to burn, and this product contains a lot of cleaning agents. 

Apart from the diesel particulate filter, it will also clean your truck’s turbo, EGR valve, and intake system.

Avoid using additives when your DPF is filled with soot. The additive will compile and add on the soot and will not solve electronic or mechanical problems.


Diesel-powered trucks have been unfriendly to the environment. To regulate the level of toxins in their emissions, DPF was invented. Diesel trucks have been popular for producing too much smoke even if the entire engine is healthy. The DPF regulates this by temporarily holding the soot. As the soot accumulates, the DPF will be clogged with time. This guide has enlightened you on two popular ways of cleaning your PDF. If you cannot get the right cleaning agent, consider taking your truck to the nearest mechanic will help you remove the soot.
