After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.

When recharging refrigerant, check for leaks.
Removal and Installation of Refrigerant Pressure SensorAJS00160
REMOVAL
1. Remove condenser. Refer to ATC-154, "Removal and Installa-
tion of Condenser" .
2. Remove refrigerant pressure sensor from condenser.
CAUTION:
When working, be careful not to damage the condenser
fins.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
Apply compressor oil to the O-ring of the refrigerant pressure sensor when installing it.
Removal and Installation of EvaporatorAJS001BJ
REMOVAL
1. Set the temperature at 18°C (60°F), and then disconnect the battery negative cable.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
3. Remove low-pressure pipe 2 and high-pressure pipe 3. Refer to ATC-151, "
Removal and Installation of
Low-pressure Pipe 2 and High-pressure Pipe 3" .
CAUTION:
Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.
4. Slide evaporator, and then remove it from heater & cooling unit.
5. Remove intake sensor from evaporator, and then remove evap-
orator.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings for A/C piping with new ones, then apply compressor oil to it when installing it.

Connection point for female-side piping is thin. So, when inserting male-side piping, take care not
to deform female-side piping. Slowly insert in axial direction.

Insert one-touch joint connection point securely until it clicks.

After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.

The O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2
(high-pressure pipe 3).

Mark the mounting position of the intake sensor bracket. Bolt mounting the high-pressure flexible hose bracket

Removal and Installation of Expansion ValveAJS001BK
REMOVAL
1. Set the temperature at 18°C (60°F), and then disconnect the battery negative cable.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
3. Remove evaporator. Refer to ATC-155, "
Removal and Installation of Evaporator" .
4. Remove mounting bolts for expansion valve, and then remove
expansion valve.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings with new ones, then apply compressor oil to them when installing them.

The O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2
(high-pressure pipe 3).

Noise InspectionAKS00BMR
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.
TYPE OF NOISE AND POSSIBLE CAUSE
Occurrence condition Possible cause
Occurs only when engine is
ON.A continuous growling noise occurs. The speed
of the noise varies with changes in the engine
speed.

Ignition condenser
A whistling noise occurs while the engine speed
is high. A booming noise occurs while the engine
is running and the lighting switch is ON.

Alternator
The occurrence of the noise is linked with the operation of the fuel pump.

Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating.A cracking or snapping sound occurs with the
operation of various switches.

Relay malfunction, radio malfunction
The noise occurs when various motors are oper-
ating.

Motor case ground

Motor
The noise occurs constantly, not just under certain conditions.

Rear window defogger coil malfunction

Open circuit in printed heater

Poor ground of antenna amplifier or
antenna feeder line

Mirror type film is attached on the rear win-
dow glass

After-market TV antenna and/or electrical
accessories such as radio are attached on
the rear window glass.
A cracking or snapping sound occurs while the vehicle is being driven, especially
when it is vibrating excessively.

Ground wire of body parts.

Ground due to incorrectinstallation of
parts.
