Everything You Need To Know About Diesel Vehicle Maintenance

Diesel vehicles revolutionized transportation when they were first introduced in 1897. From 1925 to 1927, further enhancements in the diesel engine elevated its efficiency. Over the years, these engines have become the backbone of the transportation industry whether for trucks or driving cars. The ability to handle massive loads makes them a vital component in the contemporary fleet.

However, the maintenance of diesel engines necessitates an entirely different approach than gasoline ones. Proper care and attention using the high end tools not only improve the lifespan but also enhance fuel economy, reliability, and performance. To know everything from diesel vehicle maintenance to handling troubleshooting problems, every topic is covered in this guideline discussed next.

Quick Outline: First Understand How Diesel Engines Works

Before moving toward the details of diesel vehicle maintenance, it is crucial to pay attention to how the diesel engine works. The diesel engine works differently than gasoline. It usually depends on the compression method to ignite the fuel rather than spark plugs. The higher combustion pressures make the diesel engines more efficient and powerful.

Common Diesel Engine Components

• Fuel injectors
• Diesel particulate filters
• Turbochargers
• Glow plugs

How Diesel Engine Operates

The vehicle's diesel engine works on four basic steps discussed here.

Air Intake: To draw the air into the cylinder, the piston always moves down.

Compression: It compresses air through the closing of intake valves and movement of the piston. The high temperature prepares the air for fuel ignition without any need for the spark plug.

Power Stroke: The diesel fuel is then injected into a combustion chamber using the fuel injector. The fuel mixes with the hot air causing it to ignite. The piston is pressed downwards by this mixture of high pressure air and fuel.

Exhaust: The piston starts moving upward again and the exhaust valves open. It results in the production of burnt gases that are discharged out of the exhaust.

With a higher compression ratio, diesel engines always deliver superior and efficient results and are ideal for heavy duty trucks.

Advantages of Diesel Engines

• Better fuel efficiency
• Lower carbon dioxide emissions
• Better durability
• Higher torque

Why is Diesel Vehicle Maintenance Important?

Diesel vehicles require proper maintenance to work optimally. Otherwise, neglecting regular or monthly diesel motor maintenance can lead to costly repairs, severe engine problems, and a poor fuel system.

Regular maintenance offers:

• Extended engine life
• Improved fuel efficiency
• Reduced emissions
• Better overall performance
• Lower repair costs

Fundamental Diesel Vehicle Maintenance Tips

People who love to drive diesel vehicles must take care of them for better performance and efficiency. Here is a list of top of the factory recommended maintenance tips to help make your vehicle last longer.

Clean Diesel Engine

The first and foremost tip is to clean the engine more often. When you clean the engine, you can easily locate any type of oil leakage issues or other problems before the situation gets out of hand. Moreover, the accumulation of dirt and debris on the engine shortens its life and causes corrosion if you don’t timely clean the engine.

Regular Oil Changes

The diesel engine produces more soot and contaminants. So, it is imperative to timely change the oil. It is highly recommended to change the oil every 3000 to 5000 miles to extend the longevity of your vehicle engine. Always use highly synthetic oils for better lubrication.

Brake System Inspection

Diesel vehicles wear out faster. So, it is essential to check for issues in brake pads, rotors, low levels of fluid, or any contaminants. The bad breaks can cause severe car crashes. According to the crash stats reports 22% of vehicle failures are because of bad brakes. So, whenever you observe any brake issues, instantly resolve them. If the situation is out of your hands, you can contact alphasmashrepair to solve the brake issue using high end tools and their expertise.

Fuel System Maintenance

Remember diesel vehicle fuel systems are highly complex and prone to contamination. It is suggested to use top quality diesel fuel and change the fuel after every 10,000 to 15,000 miles to prevent damage to injectors. Not only this, you should also drain water from the fuel separator to avoid performance issues.

Air Filter Replacement

It is important to remember that a clogged air filter can restrict airflow and impact vehicle efficiency. Replace the air filters to almost 12,000 to 15,000 miles or yearly basis depending on your driving situations. Driving in a dusty environment invites more air filter replacements.

Cooling Maintenance

Diesel engines run hotter, so maintaining the cooling system is also crucial. You have to check the levels of coolant because lower levels cause overheating. Additionally, it is vital to flush the radiator after every 40,000 to 60,000 miles and look for any leaks or cracks in the hoses.

Turbocharger Care

Modern engines have turbochargers which play a crucial role in high end engine performance. The pro tip for saving the turbocharger from any type of damage is to allow the vehicle engine to completely warm up and cool down before starting or stopping. Another sign of turbocharger damage is the leakage of oil into the intake system.

Diesel Particulate Filter Maintenance

If you are observing that the engine is not producing enough heat, it means there is some problem with the diesel particulate filter and it needs maintenance. The experts recommend it is necessary to clean the diesel particulate filter every 100,000 to 124,000 miles. Keep in mind, it is just a rough estimate and it depends on your driving condition. If you spend most of the time in slow driving, it quickly accumulates dirt and gets clogged.

Rotate the Tires

Check the tires for air pressure. If the pressure is low, it can decrease the fuel economy and your tires get damaged quickly. A driver can easily lose traction due to extreme pressure as well. There is a suggestion to carefully balance and rotate the vehicle tires at every oil change for better performance.

Battery Maintenance

Diesel vehicle engines require high power to get started. It puts a lot of strain on batteries. It is recommended to check for the battery voltage and clean the terminals to prevent any type of corrosion. If the battery gets too old, replace it instantly otherwise it may affect the car’s performance.

Transmission and Differential Fluid Checks

The transmission systems of diesel vehicles are heavy duty. It is good to alter the fluid every 30,000 to 60,000 miles for quality results. If the differential fluid gets dirty and breaks down, it is necessary to replace it on the spot.

Check for Dents and Scratches

To give your diesel vehicle a stunning look, you should also check for any type of dents and scratches on the exterior. The dents can be repaired with the help of the PDR method from small to extensive dents. Moreover, to get rid of scratches on the original paint, you can go for ceramic coating services.

Inspect the Glow Plugs

Whenever the oil of the engine gets changed, it is vital to inspect the glow plugs. A diesel engine leverages glow plugs instead of spark plugs to generate heat inside the cylinders. If you have bad glow plugs, your vehicle will likely not get started.

Additional Tips: Seasonal Diesel Vehicle Maintenance

Several diesel vehicle problems can arise due to seasonal transformation. So, it is necessary to keep your vehicle well maintained following the best tips based on summer and winter.

Summer Maintenance Tips

• Monitor the cooling system to check for signs of overheating.
• Check the engine thoroughly.
• Inspect the air conditioning system daily.
• Change air filters.
• Always adjust the pressure as heat expands in the tires.

Winter Maintenance Tips

• You can use special winter diesel fuel additives to avoid gelling.
• Check the block heater.
• Change the engine oil and air filter regularly.
• Always ensure glow plugs are in top condition.
• Check the health of the battery as cold days can drain the power faster.
