Low-Pressure Pipe 1 and High-Pressure Pipe 2

Removal and Installation of Low-pressure Pipe 1 and High-pressure Pipe 2

REMOVAL
1. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2. Set the temperature control switch (passenger side) at 18 degrees C (60 degrees F), and then disconnect the battery negative cable.
3. Remove cowl top cover.




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




6. 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.

7. Remove instrument passenger lower panel and glove box.
8. Remove blower unit.
9. Remove foot grille (right).
10. Remove air mix door motor (passenger side).
11. Remove mode door motor (passenger side).
12. Remove main link (right) and Max. cool door link (right).Refer to "HEATER & COOLING UNIT ASSEMBLY".




13. Remove mounting screws, and then remove evaporator cover.




14. Remove mounting bolt, and then remove low-pressure pipe 1 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, 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.
