EVAPORATOR CORE

NOTE:
- The evaporator core is not separately serviceable, it is serviced only with the evaporator core housing assembly.
- If an evaporator core leak is suspected, the evaporator core must be vacuum leak tested before it is removed from the vehicle.
- Installation of a new receiver/drier 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 receiver/drier.

The evaporator core is the plate/fin type with a unique refrigerant flow path.

- A mixture of refrigerant and oil enters the bottom of the evaporator core through the evaporator core inlet tube, continues over to the remaining five plate/fin sections, and then moves out of the evaporator core through the evaporator core outlet tube.
- This S-pass flow pattern accelerates the flow of refrigerant and oil through the evaporator core.
