Evaporator Core: Service and Repair
Overhaul
1. Pull the evaporator sensor out of the evaporator fins.
2. Remove the self-tapping screws and clips from the housing.
3. Carefully separate the housings, and remove the evaporator covers.
4. Remove the expansion valve if necessary.
NOTE: When loosening the expansion valve nuts, use a second wrench to hold the valve or evaporator pipe or they can be damaged.
5. Assemble the evaporator in the reverse order of disassembly, and:
-
Apply a thin coat of refrigerant oil to the new O-rings at joint nuts.
-
Install the expansion valve capillary tube with the capillary tube in contact with the suction line directly, and wrap it with tape.
-
Reinstall the A/C thermostat sensor in its original location.
