VQ35HR : Removal and Installation of Low-pressure Flexible Hose


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. Remove engine cover. Refer to Removal and Installation.
6. Remove air cleaner case (LH) and air duct (LH). Refer to Exploded View.





7. Remove mounting nut (A) from low-pressure flexible hose (1).

CAUTION:
Cap or wrap the joint of the A/C piping and compressor with suitable material such as vinyl tape to avoid the entry of air.
8. Remove low-pressure flexible hose.

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.
