A/C Evaporator Core Replacement

NOTE: LHD type is shown, RHD type is symmetrical.

1. Recover the refrigerant with a recovery/recycling/charging station.

1. Remove the bolt, then disconnect the suction line (A) and the receiver line (B) from the evaporator core.

1. Remove the blower unit.

1. Disconnect the connector (A) from the power transistor, then remove the wire harness clip (B), the self-tapping screws, and the expansion valve cover (C).

1. Carefully pull out the evaporator core (A) and the plate (B) without bending the pipes.

1. Install the core in the reverse order of removal, and note these items:
   - If you're installing a new evaporator core, add refrigerant oil (KEIHIN SP-10).
   - 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 correct 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.
