Buyer's checklist
What to check before buying a used radiator
- Inspect for bent or crushed fins — minor cosmetic bending is OK, but large crushed sections reduce cooling capacity.
- Check both tanks (top and bottom) for cracks, especially along the crimped seams on plastic-tank radiators.
- Confirm the inlet/outlet positions and sizes match — some models moved ports between model years.
- Look for internal blockage: shake the unit and listen for debris, or flush it with a garden hose before installing.
