Low-Pressure Pipe and High-Pressure Pipe 2

Removal and Installation of Low-pressure Pipe and High-pressure Pipe 2

REMOVAL
1. Set the temperature control dial at 18 °C (60 °F).
2. Open the driver and front passenger window, and then disconnect the battery negative cable.

CAUTION: After the battery cables are disconnected, do not open/close the driver and/or front passenger door with the window in the full up position. The automatic window adjusting function will not work and the side roof panel may be damaged.

3. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
4. Remove cowl top cover. Refer to "COWL TOP".




5. Remove mounting bolt for low-pressure flexible hose bracket.
6. Remove high-pressure pipe 1 from vehicle clips.




7. Disconnect one-touch joints.
a. Set a disconnector (high-pressure side: 92530-89908, low-pressure side: 92530-89916) 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.

8. Remove instrument passenger panel lower. Refer to "Removal and Installation".
9. Remove blower unit. Refer to "BLOWER UNIT".
10. Remove air mix door motor and mode door motor.




11. Remove evaporator cover.




12. Remove mounting bolt, and then remove low-pressure pipe and high-pressure pipe 2.

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 for A/C piping with new ones, 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.
