Buying a used heater core: what to check
- Perform low-pressure leak test: Submerge the core under water with low air pressure applied to detect pinhole leaks in aluminum tubes and tanks.
- Inspect aluminum inlet and outlet tubes: Check that connection tube ends are perfectly round and free of crushed walls or corrosion from old coolant.
- Flush internal passages with water: Run fresh water through the core to confirm no internal calcification or stop-leak additives block coolant flow.
- Confirm HVAC casing flange alignment: Verify inlet pipe bend angles and casing foam seal tracks match your vehicle's specific heater box housing.
- Replace pass-through foam seals on install: Install fresh foam sealing strips around firewall pass-through holes to prevent cold air bypass and dash squeaks.
