A/C Evaporator Core Replacement
LHD model
  1. Remove the bolt from the A/C line clamp (A).
  1. Open the clamp (A), then remove the A/C lines (B).
  1. Remove the bolt, then disconnect the A/C line (A) from the evaporator core and remove the O-rings (B).
  1. Disconnect the connectors (A) from the evaporator temperature sensor and the power transistor, then remove the connector clip (B). Remove the self-tapping screws, the expansion valve cover (C), and the seal (D).
  1. Carefully pull out the evaporator core assembly (A) without bending the lines, the remove the plate (B).
  1. Pull out the evaporator temperature sensor (A) from the evaporator core.
  1. Install the evaporator temperature sensor in the evaporator core, and note these items:
    • When the evaporator temperature sensor (A) is installed into the new evaporator core, set the sensor into the factory-preset position (B, C).
    • When the evaporator temperature sensor is reinstalled into the original evaporator core, set the sensor into the new position (D, E) because the fin may be deforming by the previous installation.
  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 (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.
