Engine Repair & Diagnostics
Diesel Engine Repair
From performance loss to full rebuilds, our techs work on major diesel engine platforms used across Class 6-8 trucks. We diagnose before we quote, so you know the actual cause before any work starts.
ECM / Computer Diagnostics
Modern diesel engines run through an engine control module (ECM) that logs fault codes long before a problem becomes a breakdown. We pull and interpret those codes to triage check-engine lights fast and accurately.
Common Failure Points We See
- Fuel system and injector issues
- Turbocharger and boost-related faults
- After-treatment system faults (DPF, SCR, EGR)
- Sensor failures triggering false or misleading codes
- Cooling system leaks and overheating
If your fault ties into a broader after-treatment or electrical issue, see also our Semi Truck Repair page.
