Duramax Diesel Repair Mechanics

We are your one stop Duramax Expert diesel repair shop servicing the Arvada metro area.

We know operating a diesel-powered vehicle is more complicated than operating any other vehicle. Whether you’re using diesel for fuel efficiency, power, or reliability, the way you maintain your vehicle will determine the type of services it’ll require.

We’ve seen it all when it comes to Duramax diesel engines – our team of ASE Certified automotive repair specialists developed a list of common Duramax service issues* they’ve seen come through our shop over the years.

Common Duramax service issues (that we can fix, of course!) include –

*Over the last 20 years, GM has built many generations of the Duramax. As such, it’s important to note some issues are unique to only one or two iterations.

Our loyal customers will tell you our team takes care of you at Colchin Automotive from the minute you call us until long after you drive your vehicle out of our garage. We guarantee it!
