Installation Notes and Tips

Verify the vehicle is a non-air-conditioning application before ordering. Match the original heater core layout and early-design requirements where noted, and compare inlet and outlet routing to the removed unit before installation. Flush the cooling system and inspect hoses, clamps, and seals during service to help protect the replacement heater core.
