EVAPORATOR

Removal and Installation

INFOID:0000000003545496

REMOVAL

1.

Remove low-pressure pipe 1 and high-pressure pipe 2. Refer to 

HA-50, "Exploded View"

.

CAUTION:

Cap or wrap the joint of the A/C piping and expansion valve with suitable material such as vinyl
tape to avoid the entry of air.

2.

Slide evaporator (1) from heater & cooling unit assembly.

3.

Remove intake sensor (2) from evaporator, and then remove
evaporator.

4.

Remove mounting bolts (A), and then remove expansion valve
(1).

CAUTION:

Cap or wrap the joint of evaporator and 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 with new ones. Then apply compressor oil to them when installing.
• 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.

• O-rings differ from low-pressure flexible hose (high-pressure pipe 1) and low-pressure pipe 1 (high-

pressure pipe 2).

• Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor

can be located in the same position.

• Check for leakages when recharging refrigerant.
