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.
