Removal and InstallationINFOID:0000000003795855
REMOVAL
1. Remove evaporator pipe assembly. Refer to HA-54, "Exploded View".
2. Slide evaporator (1) toward the right side of the vehicle (as
shown in the figure), and then remove intake sensor (2) from
evaporator.
3. Remove evaporator.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
 Replace O-rings with new ones. Then apply compressor oil to them when installing.
 Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor
can be located in the same position.
 Do not rotate the bracket insertion part when removing and installing the intake sensor.
 Check for refrigerant leakage when charging refrigerant.
