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.
