GM Duramax Repair

Chevrolet and GMC Duramax diesel repair in Langley, BC. Diagnostics, fuel systems, injectors, turbo, cooling, electrical, engine and drivetrain service.

Duramax diagnostics

Whether the complaint is a no-start, reduced power, smoke, rough running or an intermittent code, we work from scan data and physical testing to isolate the cause.

Fuel and injection system diagnosis

Low rail pressure and injector complaints are tested on both the low- and high-pressure sides so a restriction, leak, pump or injector problem is not mistaken for another.

Turbo and boost diagnosis

Boost leaks, vane-control issues, actuator faults and exhaust restrictions can feel similar from the driver seat. We test the complete air path before condemning the turbo.

Cooling system repair

We diagnose leaks, temperature-control problems, pressure buildup and other cooling complaints, including issues that only become obvious under load.

Electrical and drivability diagnosis

Duramax faults often cross engine, transmission and chassis systems. Proper scan data and circuit testing help us follow the problem instead of the code description.

Engine and drivetrain repair

If diagnosis confirms a mechanical problem, we have the equipment and shop capability for substantial engine and drivetrain repairs.
