Evaporator Case: Service and Repair

EVAPORATOR CORE HOUSING







Removal and Installation

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

1. Recover the refrigerant.
2. Remove the instrument panel.







3. Disconnect the vacuum hose.







4. Disconnect the 2 evaporator core spring lock couplings.
