SS Auto Garage handles truck trailer engine repair in Montreal for commercial vehicles and fleets. From diesel engine diagnostics to full engine overhaul service, we fix it right the first time.
Problems We Solve
A diesel engine working under commercial load puts up with a lot. Heat, weight, long hours, and hard routes all take a toll over time. When something starts going wrong, the symptoms show up gradually until they cannot be ignored. Our technicians have the experience and diagnostic equipment to get to the bottom of engine problems accurately. Here is what we fix on a regular basis:

OUR SERVICES
Our truck trailer engine repair service covers everything from targeted component fixes to full engine rebuilds for diesel trucks and heavy commercial vehicles.
Internal engine wear is gradual and affects multiple components at once. We replace pistons, valves, bearings, gaskets, seals, and timing components using parts rated for commercial diesel engines. Every replacement is done with the goal of restoring full engine performance and preventing repeat failures down the road.
Keeping a commercial fleet running efficiently starts with consistent truck engine maintenance service. We work with fleet operators to build scheduled maintenance programs around their vehicle usage and routes. Staying ahead of wear on diesel engines reduces unplanned breakdowns and keeps your fleet productive throughout the year.
Our diesel engine repair service covers a wide range of issues on heavy commercial engines, from fuel system faults and injector problems to compression loss and internal wear. We use proper fuel injector repair diesel techniques to confirm repairs before trucks return to service.
Not every damaged engine block needs full replacement. We assess cracks, warping, and bore wear carefully to determine whether truck engine rebuild or targeted block repair is the right approach. Our recommendation is based entirely on what the engine needs, and we explain the options clearly before any decision is made.
Oil leaks on commercial diesel trucks range from minor seeps to serious failures that threaten the entire engine. We locate every leak source, replace damaged gaskets and seals with quality components, and verify oil pressure and levels are within spec before your vehicle is cleared and returned to service.
A diesel engine generating commercial power produces serious heat and the cooling system has to keep up with it. We service the full cooling system including the radiator, water pump, thermostat, coolant lines, and expansion system to keep your engine running within a safe temperature range under full commercial load conditions.

Our technicians complete all required repairs including fuel injector repair, turbocharger repair, component replacements, and full truck engine rebuilds using quality commercial parts.
Before your truck leaves our shop, we run a complete engine performance repair check covering power output, oil pressure, temperature, and fuel system operation under load.
