Buyer's checklist
What to check before buying a used engine
- Confirm the VIN-matched engine code — the same model can use different engines across trims and years.
- Ask for the mileage on the donor vehicle. Under 80K miles is ideal; over 120K usually needs a compression test.
- Look for signs of overheating: warped heads, milky oil on the dipstick or filler cap, and coolant residue around the head gaskets.
- Check whether accessories (alternator, A/C compressor, power steering pump) are included or if you need to swap yours over.
