Diesel Pickups
A Duramax that is blowing white or blue smoke and running rough likely has failed injectors.
A Powerstroke blowing white smoke and losing coolant indicates failed head gaskets.
A Cummins that feels weak or lethargic may be the result of lost boost pressure, which may be a failed turbo or a leak in the charge air system.
No matter the problem, we specialize in both engine and chassis systems on your diesel truck.

Mobile Diesel and RV Repair in the Treasure Valley
When a truck cannot make it to the shop, we bring the shop to you. Our mobile diesel repair covers Boise, Meridian, Nampa, Caldwell, and Mountain Home, and our mobile RV repair reaches across the Treasure Valley and the Highway 55 corridor. The same factory diagnostic software we use in the shop goes with us on the road.
Fleet Maintenance and DOT Inspections
Fleets and owner-operators rely on us for preventative maintenance, yard checks, and annual DOT inspections that keep trucks compliant and on the road. See our fleet maintenance programs for how we plan service around your schedule.
Accurate Diagnostics Start With the Right Tools
We use factory Detroit, Cummins, and CAT diagnostic software to find the actual cause of a problem on the first visit, instead of replacing parts and hoping. That covers fuel systems, turbo systems, electrical, cooling, DEF and aftertreatment systems, and check engine lights, on heavy duty trucks and light duty diesel pickups alike.
