Diesel Repair in Sacramento

Heavy-duty diesel mechanics — not a pickup shop

Search “diesel repair” in Sacramento and half the results are shops built around pickup trucks. This isn't that. Pro Truck Services works on commercial diesels — semis, box trucks, and the working equipment that earns its keep by the mile — at our North Highlands shop and on-site where the truck sits.

Running a diesel pickup? We're built around class 7–8 trucks and commercial equipment; a light-duty diesel specialist will usually serve a personal pickup better.

What our diesel mechanics handle

• Engine diagnostics and repair — derates, no-starts, power loss, smoke, hard starts
• EGR & DPF service — the aftertreatment problems that dominate modern diesel downtime
• Fuel systems — injectors, pumps, filters, air intrusion, winter gelling
• Cooling systems, electrical diagnostics, and transmissions
• Preventive maintenance on working-truck intervals

Brands we service: Peterbilt, International, Freightliner, Dodge, Volvo, Mercedes-Benz, Kenworth, Mack, Isuzu, and Hino — with dedicated engine-platform service for Cummins, Detroit Diesel, PACCAR MX, and Volvo D-series.

Shop or roadside

Bring it to 3036 Orange Grove Ave in North Highlands — on the I-80/Watt Avenue corridor — or call for emergency and mobile diesel repair when the truck can't come to us. English and Russian spoken.

Common questions

Are you a diesel mechanic shop or a truck repair shop?

Both, because for commercial trucks they're the same job. The distinction that matters is heavy-duty versus pickup — and we're the heavy-duty side.

Do you work on diesel pickups at all?

Our bays, parts, and diagnostics are set up for commercial trucks. For a personal diesel pickup, a light-duty specialist is usually the better fit — call and we'll tell you straight either way.

Can you diagnose a diesel that has no warning lights?

Yes — plenty of diesel faults never set a code. Fuel supply, air leaks, cooling, and mechanical wear get found with testing, not just a scan tool.
