Auxiliary Climate Control

EVAPORATOR CORE







Removal and Installation

CAUTION: Refrigerant compressor oil (mineral oil) should be used to lubricate R-134a refrigerant system O-ring seals only and should not be added to the R-134a refrigerant system as an A/C compressor lubricant. PAG refrigerant compressor oil only should be used as an A/C compressor lubricant.

NOTE:
- 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.
- If an evaporator core leak is suspected, the evaporator core must be vacuum leak tested before it is removed from the vehicle.

1. Remove the auxiliary climate control housing.
2. Remove the 6 auxiliary evaporator core cover screws.
3. Remove the auxiliary evaporator core cover.
4. Disconnect the auxiliary TXV inlet fitting.
