Evaporator Components Replacement




1. Remove the filter lid (A), then pull out the dust and pollen filter (B).
2. Pull out the evaporator temperature sensor (C) from the evaporator fins.
3. Remove the screws, carefully separate the upper housing (D) from the lower housing (E), then remove the evaporator core (F).
4. If necessary, remove the expansion valve (G). Use a second wrench to hold the other fitting on the valve so the evaporator line won't twist. Leave the first fitting loosely connected so you can use it to hold the valve while you loosen the second fitting.
5. Reassemble in the reverse order of disassembly, and note these items:
- Replace the 0-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct 0-rings for HFC-134a (R-134a) to avoid leakage.
- Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
- Install the capillary tube (H) directly against the outlet line, and wrap it with electrical tape (I).
- Reinstall the evaporator temperature sensor in its original location.
- Make sure no air is leaking from the upper housing and the lower housing fitting.
