Fagan Fleet Services offers complete diesel engine diagnostics, repairs, and rebuilds for heavy-duty trucks, trailers, buses, and fleets. Whether you need a minor repair, a top-end overhaul, or a full in-frame rebuild, our technicians have the training and tools to get it done right.
Common engine repair and rebuild services include:
- Semi truck diesel engine diagnostics
- Cylinder head and gasket replacement
- Turbocharger inspection and replacement

Our process starts with a thorough inspection and computer diagnostics to pinpoint the issue.

A rebuild is often more cost-effective if the engine block is still in good condition. It allows replacement of worn components while keeping the main structure intact, restoring performance without the cost of a new engine.

With proper maintenance, a rebuilt heavy-duty diesel engine can last hundreds of thousands of miles—often as long as a brand-new engine.
