What is an Engine Overhaul?

An engine overhaul involves completely disassembling, cleaning, and rebuilding your truck’s engine. During the overhaul, our expert diesel mechanics will inspect and replace worn-out parts such as pistons, cylinders, bearings, and gaskets. This process restores your engine to factory specifications, improving performance, fuel efficiency, and reliability.

Common signs that your truck may need an engine overhaul include:

Loss of power and acceleration.

Excessive smoke or oil consumption.

Frequent overheating or engine knocking.

Significant mileage or extended use in harsh conditions.

By opting for an engine rebuild, you can avoid the high cost of purchasing a new engine while getting your truck back to peak performance.
