Description And Operation: Description
The rear heater core (1) is a heat exchanger made of rows of tubes and fins. The rear heater core is located in the Heating, Ventilation and Air Conditioning, Rear (HVACR) housing behind the right interior quarter trim panel and is retained in the housing by a plastic mounting bracket and a screw. The heater core tubes (3) are attached to the heater core tank (5) by metal retaining clamps (2) and rubber O-ring seals and are secured to the HVACR housing by a plastic flange (4).
The heater core tubes are not serviced separately from the rear heater core. The HVACR housing must be removed from the vehicle to service the rear heater core.
