VQ35HR : Removal and Installation of Low-pressure Pipe 2


REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove cowl top cover. Refer to Locations.





3. Remove mounting bolt (A) from low-pressure flexible hose bracket (1).
4. Disconnect one-touch joint between low-pressure flexible hose
(2) and low-pressure pipe 2 (3) with disconnector (B) (SST:
9253089916).

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 low-pressure pipe 1 (1) and low-pressure pipe 2 (2) with disconnector (A) (SST:
9253089916).

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 low-pressure pipe 2.

INSTALLATION
Installation is basically 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.
