Buyer's checklist
What to check before buying a used heater core
- Pressure test the core before installation to check for pinhole leaks, as dashboard removal labor makes installing a leaking used core costly.
- Inspect inlet and outlet aluminum tubes for crimping, bending, or galvanic corrosion where hoses clamp on.
- Look into the tube openings for white mineral deposits or rust scale, which indicate neglected cooling systems and clogged internal passages.
- Verify tube routing angles and quick-disconnect collar designs to ensure proper clearance through the firewall box.
