Removal and InstallationNJS000H9
REMOVAL
1. Remove low-pressure pipe 1 and high-pressure pipe 2. Refer to ATC-162, "Removal and Installation of
Low-Pressure Pipe 1 and High-Pressure Pipe 2" .
CAUTION:
Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.
2. Slide evaporator to passenger side, and then remove intake
sensor.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
Replace O-rings of A/C piping with new ones, and then apply compressor oil to it when installing
it.
Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sen-
sor can be located in the same position.
Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.
Insert piping securely until a click is heard.
After piping connection is completed, pull male-side piping by hand to make sure that connection
