High-Pressure Pipe 1 (Engine Compartment)

Removal and Installation of High-pressure Pipe 1 (Engine Compartment)

REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Remove cowl top cover.
3. Remove air cleaner assembly, air hose and air duct.
4. Remove low-pressure flexible hose.




5. Remove mounting bolt for high-pressure flexible hose bracket.




6. Remove high-pressure pipe 1 from vehicle clips.




7. Disconnect one-touch joints of high-pressure pipe 1.
a. Set a disconnector (92530-89908) on A/C piping.
b. Slide a disconnector toward (or upward) vehicle front until it clicks.
c. Slide A/C piping toward (or upward) 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.

INSTALLATION
Installation is basically the reverse order of removal.

CAUTION:
- Replace O-rings of high-pressure pipe 1 with a new ones, and then apply compressor oil to it when installing it.
- Connection point for female-side piping is thin. So, when inserting male-side piping, take care not to deform female-side piping. Slowly insert in axial direction.
- Insert one-touch joint connection point securely until it clicks.
- After piping has been connected, pull male-side piping by hand to make sure piping does not come off.
- When recharging refrigerant, check for leaks.
