• A free VIN fitment check. Our team checks your 17-digit VIN against the engine before it ships.

Used Engine with Warranty: 4 Years / 40,000 Miles

Most used engine sellers offer 30 to 90 days of coverage, and some charge extra for anything longer. At Moon Auto Parts, every used engine with warranty coverage is protected for 4 years or 40,000 miles, whichever comes first, at no added cost.

If a covered internal part fails, we work with the certified mechanic of your choice to put it right. To keep your coverage valid, have the engine installed by a licensed repair facility, register your warranty, and keep records of routine oil changes. Full terms are on our warranty page.

Eligible used engines include our 4-Year / 40,000-Mile Limited Parts-Only Warranty, whichever comes first, subject to installation, registration, maintenance, exclusions, and claim requirements — our used engines are inspected and tested prior to shipment and are sold with the mileage, condition, specifications, and warranty information shown on the applicable product page. If a covered issue arises after installation, we work directly with a certified mechanic of your choice to resolve it. Anywhere across the USA. No core charge and no return shipping hassle. Our 4-Year / 40,000-Mile limited parts-only warranty, subject to installation, registration, maintenance and claim requirements. Please review our complete Warranty Policy for details. Our warranty reflects the confidence we have in every engine we source, inspect, and sell.

How We Inspect and Grade Low Mileage Used Engines?

A used engine is only as good as the testing behind it. Before any engine is listed, it goes through a multi-point inspection:

1. Compression test on every cylinder to confirm healthy rings, valves and head gaskets.
2. OBD-II scan of the donor vehicle for stored fault codes.
3. Oil and sludge check for signs of overheating, coolant contamination or poor maintenance.
4. Mileage verification against the donor vehicle's title records.
5. Condition grading. We focus on low mileage used engines, generally under 80,000 miles, graded A or B.

Every listing shows the engine's mileage, grade and exact fitment, including displacement and VIN code, so there are no surprises when the crate arrives.

Used Truck Engines, V6, 4-Cylinder, Diesel and Hybrid Motors

We stock used motors for sale across every common fuel type and layout:

Used Engines vs. Remanufactured Engines: Which Is the Right Choice for Your Vehicle?

This is the most common question buyers ask before placing an order. Both options offer excellent value over new dealer pricing — the right choice depends on your vehicle, your budget, and how long you plan to keep the car.

Used Engines for Sale — Best Value for Most Repairs

We get a replacement engine from a vehicle that has not been driven much and sell it after we check it really well. This engine still has the parts inside, which makes it very reliable. We get these parts from vehicles that have been driven more than 80,000 miles and are in great shape. This means you can get an engine without spending too much money.

Used engines are a choice for people who have a car that is still in good condition, people who do not want to spend a lot of money, and cars that are known to be reliable, like the Honda K-series, Toyota 2AR-FE, Ford 5.0L Coyote, GM LS engines, Kia Theta II, and Hyundai Nu. Used engines are also a choice when you want to save money on repairs. You can buy a used engine from Moon Auto Parts for as low as $600. The popular engines, like the 4-cylinder and V6, cost between $900 and $2,800. This price includes a warranty and shipping.

Is a Replacement Engine the Right Repair for Your Car?

A replacement engine for sale makes the most sense when the rest of your vehicle is still solid. Ask yourself three questions:

• Is the body, frame and transmission in good condition? If yes, a new-to-you engine can add years of use.
• Is the repair cheaper than replacing the car? For most vehicles, an installed used engine costs much less than a comparable replacement car.
• Does your engine have a known design flaw? If your model is known for oil burning or timing problems, ask us whether a remanufactured unit is the safer choice.

If you're unsure, send us your VIN and a description of the failure. We'll tell you honestly which option fits.
