Diesel Engine Repair in Victoria
What we see and fix most:
- 6.7L Cummins (RAM 2500/3500): grid heater bolt failures, turbo actuator codes, injector wear, and DPF/EGR plugging on trucks that idle and short-trip around town.
- 6.7L Power Stroke (Ford Super Duty): CP4 injection pump failures (and the metal contamination that follows), turbo and EGR cooler issues, and DEF/SCR faults that derate the truck.
- 6.6L Duramax (Silverado/Sierra HD): injector and glow plug issues, DEF system faults, and CP4 pump failures on 2011–2016 LML trucks.
- 3.0L diesels (Duramax LM2/LZ0, EcoDiesel): emissions-system faults, EGR cooler problems, and the scheduled wet-belt service on the 3.0L Duramax.
Every diagnosis starts with a proper scan and inspection, and we show you what we found, photos and a written report, before any work is approved. Some diesel faults are covered by manufacturer recalls or warranty extensions (certain Cummins fuel pumps and EcoDiesel EGR coolers among them); those are VIN-specific and the remedy may sit with the dealer, and we’ll tell you straight if yours is one of them.
Diesel Maintenance
Diesels don’t need spark plugs, they need the maintenance gas engines don’t: fuel filters and water separators on schedule, the right oil and filter for your engine, DEF kept topped and clean, and cooling system care for an engine that works under load. Short trips around Victoria are hard on modern diesels. The DPF never gets hot enough to regenerate properly, so we check soot load and regeneration history at every service, not just the oil.
Dealer-alternative maintenance for work trucks, tow rigs, and daily drivers, using OEM or OEM-approved parts and fluids, and a written warranty on our work, with coverage terms that vary by vehicle class and the repair performed. Ask our service team for details on your truck.
Emissions, Chassis & Drivetrain
Most diesel breakdowns we see are emissions-system breakdowns: plugged DPFs, failed DEF heaters and pumps, EGR faults, and trucks stuck in derate or limp mode. We diagnose and repair the factory emissions system (DPF service, EGR service, DEF/SCR repair, sensors and dosing injectors) and get you out of derate without guessing at parts.
And because a diesel truck is a whole truck, we handle the rest under one roof at 677 Burnside Rd E: brakes, steering and suspension, transmissions and drivetrains, heating and A/C, tires, and electrical. Fleet and work-truck service is available, ask about priority scheduling for trucks that earn their keep.
Diesel Repair FAQ
Do you work on all three diesel brands? Yes. Cummins in RAM trucks, Duramax in GM trucks, and Power Stroke in Ford Super Duty, plus the 3.0L diesels in half-tons and SUVs (Duramax 3.0L and EcoDiesel).
My truck is in derate / limp mode. Can you fix that? Usually, yes. Derate is the truck protecting itself, most often an emissions or DEF fault. We diagnose the actual cause before replacing parts.
My DPF light keeps coming on. Do I need a new DPF? Not always. Frequent short trips prevent normal regeneration; we check soot load, sensors, and regeneration history first. A forced regen or a sensor repair may be all it needs.
Is some of this covered by a recall? Some is. Certain fuel pump and EGR cooler issues are covered on specific VINs and years. If yours qualifies, the remedy may be at the dealer at no charge, and we’ll tell you before quoting anything.
Do you service fleet diesels? Yes. Work trucks and small fleets, with maintenance plans built around keeping trucks on the road.
