Installation Notes and Tips

Verify the vehicle’s HVAC configuration before ordering, since some listed applications note w/o AC or w/o Automatic Temperature Control. Confirm the core dimensions and 3/4 in. tube sizing against the original unit before installation. Because heater core replacement often requires access through the HVAC case, inspect hoses, seals, and coolant condition during service.
