7.

Disconnect one-touch joint between high-pressure pipe 2 and 3.

a.

Set a disconnector (SST: 9253089908) 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.

8.

Remove high-pressure pipe 2.

CAUTION:

Cap or wrap the joint of high-pressure pipe 2 and 3 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 and 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.

INFOID:0000000001328225

REMOVAL

1.

Set the temperature (passenger side) at 18

°

C (60

°

F), and then disconnect the battery cable from the neg-

ative terminal.

2.

Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.

3.
