Description
DESCRIPTION
The heater core (1) is mounted into the HVAC air distribution housing, located behind the instrument panel. The heater core is a heat exchanger made of
rows of tubes and fins. The heater core is secured to the air distribution housing by a plastic retaining bracket and two screws. The heater core tubes (3)
are attached to the heater core by use of metal retaining clamps (2) and rubber O-ring seals.
The heater core tubes are not serviced separately from the heater core. The HVAC housing must be removed from the vehicle to service the heater core.
