Cons: Most pricey alternative; may not include all accessories (alternator, beginners, etc).

Remanufactured Engines

These are used engines that have been completely taken apart, cleaned, and rebuilt to OEM specs. Used parts are replaced with new components (pistons, rings, bearings, gaskets).

Pros: Perform like new engines however at a lower cost; typically included a strong guarantee (3-year/100,000 miles prevails).
Cons: Quality depends greatly on the store that performed the remanufacturing.

Utilized Engines

Sourced from salvaged lorries or “totaled” trucks, used engines are the economical option.
