Low-Pressure Pipe 1 and High-Pressure Pipe 2

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

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




4. Remove mounting bolt from 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 (SST: 9253089908), low pressure side (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 low-pressure flexible hose, low pressure pipe 1 and high-pressure pipe 1, 2 with suitable material such as vinyl tape to avoid the entry of air.

7. Remove instrument passenger lower panel and glove box.
8. Remove foot grille (right).
9. Remove air mix door motor (passenger side).
10. Remove mode door motor (passenger side).
11. Remove main link (right) and max. cool door link (right).




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




13. Remove mounting bolt, and then remove low-pressure pipe 1 and high-pressure pipe 2.

CAUTION: Cap or wrap the joint of expansion valve 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 low-pressure flexible hose, low-pressure pipe 1 and high-pressure pipe 1, 2 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.
