4.

Remove mounting bolt (1) and clamp (2), from low pressure pipe
bracket support.

5.

Remove low and high-pressure maintaining clip, from both
pipes, then remove fixing bolt (3) from low-pressure flexible
hose and low-pressure pipe 2.

6.

Remove engine room insulator fixing clip from cowl top.

7.

Pull engine room insulator, then remove pipes bracket fixing bolt
(1), from expansion valve, and release pipes fixing bracket, as
shown in order (1) to (3), from high pressure pipe 1 (B), to
remove low pressure flexible hose and pipe 2 (A) from expan-
sion valve.

CAUTION:

Cap or wrap the joint of the low pressure then remove fixing
bolt (3) pipe 2, and expansion valve exit with suitable mate-
rial such as vinyl tape to avoid the entry of air.

8.

Remove low pressure pipe 2 connector fixing nut, with suitable
tools, then remove low pressure pipe 2 (1) from low pressure
flexible hose (2).

CAUTION:

Cap or wrap the joint of the low pressure pipe 2 connector,
and low pressure flexible hose, with suitable material such
as vinyl tape to avoid the entry of air.

9.

Remove low pressure flexible hose fixing bolt (A), from air condi-
tioner compressor, and remove low pressure flexible hose (1).

CAUTION:

Cap or wrap the joint of low-pressure flexible hose 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 and low-pressure pipe 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.
