Diesel Engine Repair in Mississauga
When a truck's engine isn't running right, every hour in the shop is an hour off the road. Ontario Truck Repair diagnoses and repairs commercial truck engines at our shop at 1760 Meyerside Dr in Mississauga.
What we repair and service
We start with computer diagnostics, troubleshooting, performance analysis, emissions testing and exhaust gas analysis, so the real cause is found before parts are replaced. From there our technicians handle complete overhauls and rebuilds, turbocharger service or replacement, cooling system repairs, EGR system service and cylinder head work. We also look after fuel systems, including injector replacement and cleaning, fuel pump service, fuel line repairs and fuel tank inspection, along with timing belt or chain replacement, aftertreatment systems (DEF/DPF), oil leak diagnosis, oil cooler replacement and glow plug replacement.
Signs your truck may need engine repair
- A check engine or aftertreatment warning light on the dash
- Loss of power or poor fuel economy
- Hard starting or a rough idle
- Heavy smoke from the exhaust
- Overheating, coolant loss or oil leaks
Why it pays to fix it early
Small engine problems rarely stay small. A minor oil leak, a weak injector or a clogged DPF can turn into a major repair if the truck keeps working, and a breakdown on the road costs far more than a planned shop visit. Dealing with warning signs early keeps repair costs more predictable and protects the engine over the long run.
