Diesel Repairs

Is your car noisy or producing excessive smoke? These are two signs that indicate you need engine repair. Although they are very durable and reliable, diesel engines still break down just like any other engine. At the first sign of any problem, it’s important to bring your vehicle to Expertec Automotive for diesel engine repair. We know these types of engines inside and out. Since we are skilled at repairing all types of problems, you can trust our technicians to ensure the repair job is done right the first time.

Diesel engines operate differently from gas engines so not all auto repair shops are equipped to provide diesel engine repair. Before you let just any auto technician tinker with your vehicle, turn to our expert specialists for accurate and comprehensive diesel repair. We are qualified technicians that have extensive experience in diesel car repair.

It takes more than the proper tools to repair a diesel engine. As highly-skilled mechanics, we take pride in diagnosing any engine problem and providing affordable repairs. Whether you have a small diesel car or big pickup truck, you can depend on Expertec Automotive to get you back on the road again.

Signs Your Diesel Car May Need Repairs

If your car or truck sounds louder than a motorcycle? The chances are likely that it needs diesel car repairs. By repairing or replacing glow plugs, fuel injectors, turbochargers, and other engine components, we ensure that your vehicle stays running for the long haul. Other symptoms that indicate engine problems include:

  • Stalling Problems
  • Lower Running RPMs
  • Electrical Problems
  • Excessive Smoke
  • Acceleration Issues
  • Engine Is Difficult To Start
  • The Differences Between Diesel and Gas Engine Repair


Unlike gasoline engines, diesel engine systems use their own compression to ignite fuel. They have significantly more compression in the chamber than gas-powered engines. This means that the air-to-gas mixture is very different as well. Due to the extreme compression, external sparking is not necessary. Built without spark plugs, a diesel engine runs more efficiently using glow plugs. Many of the new models get 500,000 miles without the need for a rebuild.

At Expertec Automotive we also offer Diesel Induction Service

Diesel fuel will oxidize and form residues that deposit in fuel injectors and combustion chambers. These deposits will drastically affect the engines performance by clogging fuel injectors and creating irregular spray patterns. This service is designed for concentrated cleaning of the injection pump and injectors. At least once a year or when fuel related issues are present in a diesel fuel injection.

If you feel your diesel vehicle is in need of service or repair, come to Expertec Automotive and let one of our ASE certified technicians take a look and your diesel vehicle.
