Overhaul
Evaporator Overhaul1. Pull the A/C thermostat 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 expansion valve or evaporator pipe, otherwise, they can be damaged.
- Assemble in the reverse order of disassembly, and:
^ Replace the all 0-rings with new ones at each fitting, and apply a thin coat of refrigerant oil (SP-10: P/N 38899-P13-AO 1) before installing them.
NOTE: Be sure to use the right 0-rings for HFC-134a (R-134a) to avoid leakage.
^ 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 to its original location.
