Heater Core: Description

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

The heater core is mounted in the HVAC housing, located behind the instrument panel. The heater core is a heat exchanger made of rows of tubes and fins. The heater core inlet and outlet tubes are integral to the heater core and cannot be serviced separately. See Fig 1.

The heater core can be serviced by removing the HVAC housing from the vehicle.
