Diesel Truck Repair in Prince George

Cummins. Powerstroke. Duramax. Diesel trucks work harder than gas engines and fail differently. Lug Nutz does the injector work, the turbo replacements, the DPF service, and the full engine rebuilds on work trucks.

What we do

The full job. Not a patch.

Injector replacement is the most common big job. Bad fuel, worn seals, or high mileage catch up with diesels. We pull, test, and install new sets.

Turbo failure runs a close second. Bearing wear, oil starvation, or damage from a bad boost leak. Full turbo replacement including piping and clamps.

DPF and emissions work. Regeneration failures. NOx sensor faults. Legal cleaning. We do the work that keeps the truck compliant.
