Repair, Replacement, and Rebuilding of Heavy-Duty Truck Diesel Engines

From Diagnostics to a Complete Rebuild of Your Diesel Engine

MT Service Routier offers comprehensive diagnostic, repair, replacement, and rebuilding services for heavy-duty truck diesel engines, fleets, and commercial vehicles in Mirabel and on the North Shore.


Our
garage addresses issues such as loss of power, excessive smoke, overheating, oil consumption, leaks, loss of compression, engine codes, injection problems, and major repairs.


We evaluate each engine to determine whether a targeted repair, an in-frame repair, an overhaul, or a complete replacement is the best solution.
