Used Engine Cost: What You Should Pay in 2026
A used engine from a salvage yard usually runs $400 to $2,500 depending on the engine and its mileage — roughly 50% to 70% less than a new one. The trade-off is condition: you are buying a part with miles on it, so the donor vehicle and the warranty matter more than the sticker price.

Used vs remanufactured vs new
A used engine is pulled from a donor car and sold as-is. A remanufactured engine has been torn down and rebuilt to spec with new wear parts, which is why it costs more and carries a longer warranty. New OEM is the most expensive and rarely worth it on an older vehicle.
For a car worth less than about $6,000, a used engine is almost always the right call. The money you save covers the small risk you take on mileage.
Labor to install an engine
A shop will charge roughly $1,000 to $2,500 in labor to swap an engine, depending on whether it is front- or rear-wheel drive and how buried the engine is. Doing it yourself drops that to $0 plus a weekend and an engine hoist.
Before you buy a used engine
- check_circleMatch the 8th digit of the VIN (engine code) to your vehicle.
- check_circleAsk the donor mileage and the reason the car was scrapped.
- check_circleCheck the oil cap and dipstick for milky "milkshake" residue (blown head gasket).
- check_circleGet the warranty terms in writing — even 30 to 90 days helps.
- check_circleConfirm the engine interchange so you can pull from more donor cars.
Frequently asked questions
How much does a used engine cost?expand_more
