Why Taking Your Diesel to a Specialized Repair Shop Is Important

When you drive a diesel-powered truck or car, taking it in for diesel repair may mean having to go to a shop specializing in diesel engines. The differences between a diesel engine and a gasoline engine can be significant when there is something not working correctly, so working with a shop that is familiar with them can be the best option.

1. Diesel Engine Systems

The engine in your diesel car or truck shares many of the same systems as most gasoline engines, but the way a diesel engine runs is different, so these systems work differently. A traditional gas engine uses a spark to fire the engine's fuel load, but that is not the case with a diesel.

Understanding the fuel system, injector pump, and injector system is crucial because they are different from those of a gas engine. The diesel engine is far more affected by cold temperatures, and fuel with impurities can stop the engine from running at all. 

If you are having trouble with your diesel engine running correctly, a diesel repair tech will need to go over the systems to determine what is causing the issue. Often the diagnostic process is different, so working with a shop that understands that is critical. 

2. Critical Filters

Diesel engines are extremely dependant on air and fuel flow, and a dirty air filter can significantly impact the way the engine runs. The air filters for your diesel engine must be inspected and cleaned regularly so that the engine efficiently and power stays at peak levels. 

Along with the air filters, a diesel engine has several fuel filters that need attention. The diesel repair shop that services your truck can replace the fuel filters when they change the oil filters on the engine but depending on the truck, the fuel used, and the filter used; they may be able to do it every other oil change. 

The fuel filters are large filters that look a lot like oil filters, but they are designed to remove particles and debris from the fuel before they get to the injector pump. Even a small particle of dirt in the injector pump can cause the engine not to run right. 

3. Turbo Systems

Many diesel engines are turbocharged and may have an intercooler to reduce the air temperature passing through the turbo. This system is vital for your diesel, and the turbo needs to be maintained to retain the boost it adds to the engine. 

When you take your diesel truck or car into a diesel repair shop, they will check the turbo for proper operation and wear. Often this is part of regular maintenance for a diesel, but if you have a particular concern about the system, let the tech know.
