Computer Diagnostics

We use the latest in technology to ensure that your heavy duty diesel engine gets the best care that is possible.  We’ll have one of our certified mechanics diagnose the problem and then fix the issue to make sure you’re back up and running as soon as possible.

Heavy Duty Diesel Engines have very critical and high cost services that come with them.  These can lead to serious economical impacts to your business.  We can ensure that diagnostics are performed during both preventive maintenance and when you have engine failure. Because of their complexity, these heavy duty engines require expertise from a certified computer diagnostic technician and at Coy’s Heavy Duty we can have a staff that is trained to do just that.  Diagnose the problem and get your engine running properly in the least amount of time possible.
