Full-service engine repair in Calgary

Full rebuilds and recon engines for gas and diesel platforms, backed by a written warranty on the work and the parts.
Head Gasket Repair
Blown or failing head gasket? We diagnose it properly and repair it right — no guesswork, no shortcuts.
Engine Diagnostics
Computer diagnostics plus a hands-on inspection, so you get a clear answer on repair vs. replace before any work starts.

Engine Overheating
Chronic overheating usually points to something specific. We find the actual cause instead of just topping up coolant.
