Buyer's checklist
What to check before buying a used starter
- Match the bolt pattern and nose cone length — starters from the same engine family may physically bolt up but not engage the flywheel correctly.
- Check the solenoid for corrosion on the electrical terminals.
- Ask whether it was bench-tested. A starter should crank firmly without excessive draw.
- Verify the tooth count on the drive gear matches your flywheel or flexplate.
