HIGH-PRESSURE PIPE 1(ENGINE COMPARTMENT)

3.

Remove high-pressure pipe 1 (1) from vehicle clips (A).

4.

Disconnect one-touch joint between high-pressure pipe 1 (1)
and high-pressure pipe 2 (2) with disconnector (A) (SST:
9253089908).

CAUTION:

Cap or wrap the joint of high-pressure pipe 1, 2 with suit-
able material such as vinyl tape to avoid the entry of air.

5.

Disconnect one-touch joint between high-pressure pipe 1 and
condenser pipe assembly with disconnector (A) (SST:
9253089908).

CAUTION:

Cap or wrap the joint of high-pressure pipe 1 and con-
denser pipe assembly with suitable material such as vinyl
tape to avoid the entry of air.

6.

Remove vacuum hose. Refer to 

BR-37, "Removal and Installation"

.

7.

Remove high-pressure pipe 1.

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

• Replace O-rings of high-pressure pipe 1 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.
