Evaporator Core: Description and Operation

NOTE: Installation of a new suction accumulator/drier is not required when repairing the air conditioning system except when there is physical evidence of system contamination from a railed A/C compressor or damage to the suction accumulator/drier.

The A/C evaporator core is the plate/fin type with a unique refrigerant flow path.
^ A mixture of refrigerant and oil enters the bottom of the A/C evaporator core through the A/C evaporator core inlet tube, is routed so it flows through the plate/fin sections, then moves out of the A/C evaporator core through the A/C evaporator core outlet tube.
