A/C Evaporator Core Replacement

NOTE: LHD type is shown, RHD type is symmetrical. Recover the refrigerant with a recovery/recycling/charging station. Remove the bolt, then disconnect the suction line (A) and the receiver line (B) from the evaporator core. Remove the blower unit. |

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). |

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