Evaporator Core: Description and Operation
Front A/C Evaporator - Description
DESCRIPTION
The A/C evaporator for the front heating-A/C system is located in the front HVAC housing, behind the instrument panel. The A/C evaporator is made of
rows of flat tubes with fins (4). The A/C expansion valve is attached to the evaporator tubes (2) by use of a metal tapping plate (3) and rubber and metal
composite dual-plane seals. The A/C evaporator and insulator (1) are positioned in the HVAC housing so that all air flowing through the housing must
pass through the evaporator before it is distributed through the heating-A/C system ducts and outlets. However, air passing through the A/C evaporator
will only be conditioned when the A/C compressor is engaged and circulating refrigerant through the evaporator.
The HVAC housing must be removed from the vehicle and disassembled to service the A/C evaporator.
