Installation Notes and Tips

Verify the vehicle is equipped without air conditioning before ordering, since the fitment listed here is specific to non-AC applications. Compare the inlet and outlet pipe diameters, along with the core height, width, and thickness, to the original unit before installation. Flush the cooling system and inspect hoses, clamps, and seals so the new heater core is not exposed to contamination from the rest of the system.

Quality Assurance

APDI supplies replacement HVAC components built to match the listed application details and dimensional specifications. Confirm fitment against the vehicle year, make, model, and heater configuration before installation.
