We Know Diesel

Typically, when people think of diesel engines, they think of the piston-pumping power, but there are actually a lot of brains behind that brawn. Many of our team members are certified diesel technicians. These are the type of guys that dream of tight gaskets, purring engines, perfectly lubricated crankcases, and that sweet, musky aroma.

Our certified diesel techs are expertly trained to diagnose and repair any diesel engine. Whether it’s an emergency repair or regularly-scheduled visit, we’re proud to be the best place to take your diesel truck.

Fleet Maintenance for Diesel Vehicles

Whether it’s a single diesel truck or an entire fleet, we can handle all of your maintenance needs. We offer quarterly and annual preventative fleet maintenance programs, as well as regular cleanings.

Diesel Repairs

Using state-of-the-art scan tools, we can diagnose and repair virtually every problem related to your diesel truck. We can work on your vehicle’s suspension, front end, water pumps, differentials, as well as overhaul your transmission and engine.

Licensed Government Inspections

As a facility licensed by the Ministry of Transportation, we can offer commercial safety inspections, out-of-province inspections, insurance inspections, as well as general inspections simply for your peace of mind.
