Important Information

Donor Used Engine – No Applied Warranty

This is a used donor engine removed from a running vehicle or sourced for parts. Due to the age, mileage, and unknown service history of used components, this engine is sold as-is with no applied warranty, express or implied.

We recommend inspecting the engine before installation and replacing normal maintenance items (such as seals, gaskets, timing components, and water pump, where applicable) prior to use. Professional installation is strongly recommended.
