Low-Pressure Flexible Hose

Removal and Installation of Low-pressure Flexible Hose

REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove the air cleaner case and air duct. Refer to "AIR CLEANER AND AIR DUCT" (VQ35DE) or "AIR CLEANER AND AIR DUCT" (VK45DE).




3. Remove low-pressure flexible hose bracket mounting bolt.




4. Disconnect one-touch joint between low-pressure flexible hose and low-pressure pipe 1.
a. Set a disconnector (SST: 9253089916) on A/C piping.
b. Slide a disconnector toward vehicle front until it clicks.
c. Slide A/C piping toward vehicle front and disconnect it.

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




5. Remove mounting nut from low-pressure flexible hose.




6. Remove mounting nut, and then remove low-pressure pipe (VK45DE).
7. Remove low-pressure flexible hose.

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

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.
- 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 does not come loose.
- When recharging refrigerant, check for leaks.
