INSTALLATION
Install liquid tank, and then install liquid tank bracket on condenser.
CAUTION:
●
Make sure liquid tank bracket is securely installed at protru-
sion of condenser.
●
Make sure liquid tank bracket does not move to a position
below center of liquid tank.
●
Replace O-rings of A/C piping with new ones, and then
apply compressor oil to it when installing it.
●
When recharging refrigerant, check for leaks.
Removal and Installation of Condenser
NJS0004M
REMOVAL
1.
Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
2.
Remove engine cover, using power tools. Refer to
EM-18, "INTAKE MANIFOLD COLLECTOR"
3.
Remove air cleaner assembly, air hose and air duct. Refer to
EM-16, "AIR CLEANER AND AIR DUCT"
4.
Remove engine under cover, using power tools.
5.
Drain engine coolant. Refer to
6.
Remove radiator fan shroud with cooling fan after removing radi-
ator upper hose. Refer to
7.
Remove radiator reservoir tank and radiator reservoir tank
bracket. Refer to
.
8.
Remove ambient sensor bracket after removing horn (right
side). Refer to
.
9.
Disconnect high-pressure flexible hose and high-pressure pipe
1 from condenser.
a.
Set a disconnector [condenser outlet (SST: 9253089908), con-
denser inlet (SST: 9253089912)] on A/C piping.
b.
Slide a disconnector upward until it clicks.
c.
Slide A/C piping upward and disconnect it.
CAUTION:
Cap or wrap the joint of condenser, high-pressure flexible
hose and high-pressure pipe 1 with suitable material such
as vinyl tape to avoid the entry of air.
10. Remove mounting bolts from condenser.
Liquid tank bracket mounting bolt (upper side)
: 3.4 N·m (0.34 kg-m, 30 in-lb)
Liquid tank bracket mounting bolt (lower side)
: 5.7 N·m (0.58 kg-m, 50 in-lb)

REFRIGERANT LINES
11. Remove radiator upper mount, move radiator and condenser to the engine side.
12. Lift condenser up slightly and tilt it toward front of vehicle. (This
is because condenser lower bracket is on bottom of radiator
tank.)
13. Pull condenser forward at an angle. Remove condenser from
radiator.
CAUTION:
Be careful not to damage the core surface of condenser and
radiator.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
●
Replace O-rings of high-pressure flexible hose and 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.
Removal and Installation of Refrigerant Pressure Sensor
NJS0004N
REMOVAL
1.
Remove condenser. Refer to
ATC-147, "Removal and Installation of Condenser"
.
2.
Remove refrigerant pressure sensor from condenser.
CAUTION:
When working, be careful not to damage the condenser.

Removal and Installation of Evaporator
NJS0004O
REMOVAL
1.
Remove low-pressure pipe 2 and high-pressure pipe 2. Refer to
ATC-144, "Removal and Installation of
Low-pressure Pipe 2 and High-pressure Pipe 2"
.
CAUTION:
Cap or wrap the joint of evaporator, low-pressure pipe 1, 2 and high-pressure pipe 1, 2 with suit-
able material such as vinyl tape to avoid the entry of air.
2.
Slide evaporator, and then remove it from heater & cooling unit
assembly.
3.
Remove intake sensor from evaporator, and then remove evap-
orator.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
●
Replace O-rings of evaporator, low-pressure pipe 1, 2 and high-pressure pipe 1, 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.
●
O-rings are different from low-pressure pipe 1 (high-pressure pipe 1) and low-pressure pipe 2
(high-pressure pipe 2).
●
Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sen-
sor can be located in the same position.
●
When recharging refrigerant, check for leaks.
Refrigerant pressure sensor
: 10.8 N·m (1.1 kg-m, 8.0 ft-lb)

Removal and Installation of Expansion Valve
NJS0004P
REMOVAL
1.
Remove evaporator. Refer to
ATC-149, "Removal and Installation of Evaporator"
.
2.
Remove mounting bolts, and then remove expansion valve.
CAUTION:
Cap or wrap the joint of evaporator with suitable material
such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
●
