Installation Notes and Tips

Verify the vehicle is equipped without air conditioning before ordering, since this heater core is listed for non-AC applications. Confirm inlet and outlet pipe diameters, core dimensions, and hose routing against the original unit before installation. Flush the cooling system and inspect hoses, clamps, and the heater control valve, if equipped, before fitting the new core.

Quality Assurance

APDI supplies replacement HVAC components for vehicle-specific service applications. This heater core is built with aluminum construction and application-matched dimensions for the listed GM fitments, including Chevrolet Monte Carlo, Buick Regal, and Pontiac Grand Prix models.
