Diesel and Work Truck Repair in Klamath Falls
We work on light duty diesel and on three quarter ton and one ton pickups, including Duramax, Power Stroke, and Cummins.
In this basin a truck is usually a working vehicle, which means downtime costs money. We tell you honestly whether a job is one we should take on or one that belongs somewhere else.
We book by phone, so you get a real answer about timing.
What it costs to find out
Noise and leak inspections are free
Noise, front end, exhaust, and leak inspections are free on trucks the same as anything else. Scanner diagnostics carry a fee we quote before you come in.
