Why Your Diesel Engine Requires Special Care

When compared to Gasoline, Diesel engines are:

Slower to evaporate
Higher in energy density

Owing to these factors, diesel engines deliver better mileage than gas engines. Diesel engines emit minimal amounts of greenhouse gases such as carbon monoxide that lead to global warming. Still, they emit relatively high amounts of soot and nitrogen compounds that cause acid rain and other issues.


Both diesel and gas engines are internal combustion engines that convert fuel into energy. Combustion allows the machines to work in a series of small explosions and this is where the two engines differ. 


Gas engines operate when fuel is mixed with air, then compressed by pistons and ignited by spark plugs. Diesel engines compress the air before injecting the fuel directly into the combustion chamber. Air heats up when it’s compressed, so the fuel in diesel engines ignites without the use of sparks—our diesel engine services in Calgary including this kind of direct injection. 


Proper maintenance is key to ensuring the longevity and optimal performance of your diesel truck. Here are some essential maintenance tips to keep your diesel truck running smoothly:

  • Regular Oil Changes: Diesel engines require regular oil changes to keep them running smoothly. Be sure to use the recommended oil grade and change it at the manufacturer's recommended intervals.

  • Fuel Filter Replacement: The fuel filter in your diesel truck plays a crucial role in preventing contaminants from entering the engine. Replace the fuel filter regularly to ensure clean fuel is reaching the engine.

  • Air Filter Replacement: The air filter is responsible for filtering out dust and debris from the air before it enters the engine. A dirty air filter can reduce engine performance and fuel efficiency. Replace the air filter according to the manufacturer's recommendations.

  • Coolant System Maintenance: The cooling system is essential for regulating the temperature of your diesel engine. Regularly check the coolant level and condition, and flush the system as recommended by the manufacturer.

  • Regular Inspections: Regularly inspect your diesel truck for any signs of wear or damage, such as leaks, worn belts, or loose hoses. Addressing these issues promptly can prevent more significant problems down the road.

  • Professional Maintenance: While there are many maintenance tasks you can perform yourself, some tasks require the expertise of a professional technician. Regularly schedule maintenance checks with a qualified diesel truck repair specialist to keep your truck in top condition.

By following these maintenance tips, you can help ensure that your diesel truck remains reliable and efficient for years to come. Contact Change Auto & Diesel to help you with more maintenance tips and diesel truck repair services in Calgary.


Despite their durability, diesel trucks can still experience mechanical issues that require repair. Here are some common diesel truck repairs you may encounter in Calgary:

  • Injector Problems: Diesel fuel injectors can become clogged or malfunction, leading to issues such as rough idling, reduced performance, and increased fuel consumption. Injector cleaning or replacement may be necessary to resolve these issues.

  • Turbocharger Failure: The turbocharger in a diesel engine can fail due to issues such as oil contamination, wear and tear, or overheating. Turbocharger replacement may be required to restore engine performance.

  • EGR Valve Issues: The EGR (Exhaust Gas Recirculation) valve helps reduce emissions by recirculating exhaust gases back into the engine. However, the EGR valve can become clogged or fail, leading to issues such as poor engine performance and increased emissions.

  • DPF (Diesel Particulate Filter) Problems: The DPF is designed to trap and remove harmful particulate matter from diesel engine exhaust. However, the DPF can become clogged over time, leading to issues such as reduced engine performance and increased emissions. Cleaning or replacement of the DPF may be necessary.

  • Glow Plug Failure: Glow plugs are essential for starting a diesel engine, especially in cold weather. If glow plugs fail, the engine may be difficult to start or may not start at all. Glow plug replacement may be required to resolve this issue.

  • Electrical System Issues: Like any vehicle, diesel trucks can experience electrical system issues such as faulty wiring, dead batteries, or malfunctioning alternators. Proper diagnosis and repair by a qualified technician are necessary to address these issues.

Being aware of these common diesel truck repairs and addressing them promptly can help ensure that your diesel truck remains reliable and efficient for years to come. Our expert technicians can help you with complete diesel truck repairs for all types of trucks in Calgary.
