Installation Notes and Tips

Verify the inlet and outlet pipe diameters before installation and compare the replacement core to the original unit for fitment. Because heater core replacement often requires access through the HVAC case, inspect hoses, seals, and surrounding components for wear before reassembly. Flush the cooling system if contamination or sediment is present to help protect the new core.
