Our technicians will use a diagnostics approach in locating the problem and will systematically test various systems and components to ensure that they are working properly. By doing so, through elimination, experienced mechanics are able to isolate the component or system that is causing the problem.  Our shop technicians also test drive a vehicle to determine a problem. They are skilled in the use of a variety of testing equipment, including onboard computer systems and handheld diagnostic computers.

Want a fuel economy boost? Our technicians can check your diesel engine, look at quality of exhaust flow with back pressure check tests, run diagnostics on the fuel injection system, check your turbocharger, and more, to determine efficiencies and inefficiencies in the various systems and suggest your best options for increased fuel economy.

With years of experience in diesel trucks and auto engine repair, our team is not only able to diagnose and fix any problem, but they also can prescribe maintenance measures to prevent future problems that may arise. If you are interested in scheduled maintenance or fleet maintenance please give us a call and we can set you up. We serve to meet any repair need you may have. Cummins Automotive & Diesel Service will repair your vehicle so you can get back to work.
