2. Reliable — Our used engines undergo numerous tests before they reach you. They are tried and tested under the toughest conditions, saving you money on future repairs.

3. Hassle-Free — Buying a new car is a real hassle. You have to deal with registration, insurance, and high costs. With a used engine, you skip all that and get your car running for under $500.

4. Warranty Coverage — All our engines come with 1–3 years of warranty or extended coverage, removing the risk from buying used parts.

5. Join the Cause — Reduce waste and help the planet. Used engines and transmissions you buy from Used Auto Parts prevent thousands of parts from ending up in landfills, making Earth a cleaner place.

1. Mileage on the Engine — Mileage is a crucial factor affecting the engine's life expectancy. Ideally, an engine should have covered around 15,000 miles per year. Always calculate the total mileage relative to the age before making a decision.

2. Proper Testing — Ensure the engine has undergone proper tests. Our engines are tested twice: first, a run test to check performance across different operating conditions, and second, a compression test to assess the condition of valves, valve seats, and piston rings.

3. Compatibility — Confirm that the engine will fit your vehicle. Provide the make, model, and year of your car, SUV, truck, or motorcycle to ensure proper compatibility.

4. Warranty — Always request a warranty. Check for any conditions on the warranty and ensure you have coverage from our suppliers before completing the order.
