CAUTION:
Perform lubricant return operation before each refrigeration system disassembly. However, if a large amount of refrigerant or lubricant is detected, never perform lubricant return operation. Perform Lubricant Return Operation.

REMOVAL

1.Remove low-pressure pipe. Exploded View.
2.Remove air cleaner case LH and air duct LH. Exploded View
3.Remove mounting bolt from low-pressure flexible hose. Exploded View.





4.Disconnect one-touch joint between high-pressure pipe (1) and condenser pipe assembly (2) with disconnector (A) (SST: J45815).

CAUTION:
Cap or wrap the joint of the A/C piping with suitable material such as vinyl tape to avoid the entry of air.





5.Disconnect one-touch joint between high-pressure pipe (1) and high-pressure evaporator pipe (2) with disconnector (A) (SST: J45815).

CAUTION:
Cap or wrap the joint of the A/C piping with suitable material such as vinyl tape to avoid the entry of air.
6.Remove high-pressure pipe from the vehicle.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:
- Replace O-rings with new ones. Then apply compressor oil to them when installing.
- 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 check that connection does not come loose.
- Check for leakages when recharging refrigerant. Leak Test.
