Engine fitment can be verified with the notes and ‘Vehicle Fitment’ tab above, or with the casting numbers under ‘Specifications’ (if applicable), or by calling 256-913-8001.
Every engine we sell is fully remanufactured to meet or exceed OEM specifications:
Clean – To start the remanufacturing process, every engine is fully disassembled and hot tanked (cast iron) or thermally cleaned (aluminum)
Inspection – We check for microscopic cracks and fissures that will cause long-term failure. All parts are visually inspected as well.
Machining and New Parts – Deck surfaces are machined and new parts are added. New parts include bearings, pistons, rings, lifters, oil pump, gaskets, valve seals, freeze plugs, galley plugs and either a new timing chain (with new tensioners) or a new timing belt (with new tensioner). If an engine has a timing-driven water pump, a new pump is installed.
Testing – Each engine is tested after reassembly, with the cooling and oil systems being fully pressurized and the crank being spun at high RPM to verify compression and build quality.
Each engine comes with up to 3 years and 36,000 mile warranty, which can be upgraded upon checkout.
