A remanufactured engine
An engine that has been restored to as close to new as possible. The engine is thoroughly inspected and damaged or worn parts are replaced with new or re-machined parts that meet original equipment manufacturer (OEM) specifications. There are zero miles on a remanufactured engine.
A used engine
Most used engines are pulled out from wreckages or yard-bound vehicles. The mileage on these engines could be high or low depending on how long they were run previously. As they have served part of their life in a different car, they can be an inexpensive option for some car owners. Used engines sourced through Colorado Engine come with a certificate of mileage and a nationwide 6 month part warranty.
