REMOVAL
1. Remove the evaporator. Refer to VTL-41, "Removal and Installation of Evaporator".
CAUTION:
Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.
2. Remove the intake sensor (1) from the evaporator (2).
CAUTION:
Mark the position of intake sensor on the evaporator for
installation.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
 Replace O-rings for A/C piping with new ones, and then apply compressor oil to it when installing it.
 Install the intake sensor in the same position as the original intake sensor.
 When recharging refrigerant, check for leaks.
