Evaporator Removal and Installation
1. Recover the refrigerant with a recovery/recycling/charging station.
2. Disconnect the suction tine (A) and receiver line (B) from the evaporator. Remove the mounting nut. Plug or cap the lines immediately after
disconnecting them to avoid moisture and dust contamination.
3. Remove the glove box.
4. Remove the plastic cross brace, then remove the glove box frame.
5. Remove the wire harness connectors (A). Disconnect the evaporator temperature sensor connector (B). Remove the self-tapping screws, the
mounting nuts, the mounting bolts, the bracket (C) and the evaporator (D).
6. Install the evaporator in the reverse order of removal, and note these items.
-
If you're installing a new evaporator, add refrigerant oil (DENSO ND-OIL 8).
-
Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right
O-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.
-
Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
-
Make sure that there is no air leakage. Charge the system.
