Evaporator Core: Description and Operation

A/C EVAPORATOR CORE

NOTE:
- Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator.
- The evaporator core is serviced as a core and housing assembly. The evaporator core, internal doors, seals and door linkage are included with the housing.

The A/C evaporator core is the plate/fin type.
- The A/C evaporator core is located inside the vehicle in the evaporator core housing.
- A mixture of refrigerant and oil enters the bottom of the A/C evaporator core through the A/C evaporator core inlet tube and then moves out of the A/C evaporator core through the A/C evaporator core outlet tube.
- During A/C operation, air from the blower motor is cooled and dehumidified as it passes through the evaporator core fins.
