TEST
M1552008400378
1. Start the engine.
2. Operate the air-conditioner, and then set the
temperature to maximum cooling.
3. Hold the engine speed at 1500 r/min.
4. Check the refrigerant level (bubble state) through
the sight glass.
CAUTION
Use the low-pressure service valve.
NOTE: Use the refrigerant recovery station to
charge the specified refrigerant because you can
not calculate the amount of the refrigerant
properly with the sight glass.
MAGNETIC CLUTCH TESTM1552008500405
1. Disconnect the magnetic clutch connector to the
magnetic clutch.
2. Connect positive battery voltage directly to the
connector for the magnetic clutch.3. If the magnetic clutch is normal, there will be a
"click." If the pulley and armature do not make
contact ("click"), there is a malfunction.

DUAL PRESSURE SWITCH CHECKM1552010400320
1. Remove the dual pressure switch connector and
connect the high/low pressure side terminals
located on the harness side as shown in the
illustration..
2. Install a gauge manifold to the high-pressure side
service valve of the refrigerant line. (Refer to
P.55-98, P.55-99.)
3. When the high/low pressure sides of the dual
pressure switch are at operation pressure (ON)
the resistance should less than two ohms
between the terminals. If open circuit, replace the
switch. Items State
Insufficient Many bubbles are seen.
If refrigerant is extremely
low, it appears white.
Sufficient or excess

IDLE-UP OPERATION CHECK
M1552001600371
1. Before inspection and adjustment, set vehicle in
the following condition:
•Engine coolant temperature: 80 − 90 °C•Lamps, electric cooling fan and accessories: Set
to OFF
•Transmission: Neutral ("N" or "P" for vehicles with
A/T)
•Steering wheel: Straightforward
2. Check whether or not the idle speed is the
standard value. <1300, 1600> Refer to GROUP
13A, On-vehicle Service − Basic Idle Speed
Adjustment P.13A-387.
<2000> Refer to GROUP 13B, On-vehicle Service
− Basic Idle Speed Adjustment P.13B-324.
Standard value: 750 ± 50 r/min
3. When the A/C is running after turning the A/C
switch to ON, and the blower switch to the 3(MH)
or 4(HI) position, check to be sure that the idle
speed is at the standard value.
Standard value: 850 ± 50 r/min
NOTE: It is not necessary to make an adjustment,
because the idling speed is automatically
adjusted by the ISC system. If, however, a
deviation from the standard value occurs for some
reason, check the ISC system.

COMPRESSOR ASSEMBLY AND TENSION PULLEY
HEATER, AIR CONDITIONER AND VENTILATION55-93
INSTALLATION SERVICE POINT
>>A<< A/C COMPRESSOR
INSTALLATION
If a new compressor is installed, first adjust the
amount of oil according to the procedures described
below, and then install the compressor.
1. Measure the amount (X mL) of oil within the
removed compressor.
2. Drain (from the new compressor) the amount of
oil calculated according to the following formula,
and then install the new compressor.
New compressor oil amount = 140mL <1300,
1600>, 120 mL <2000>
140 mL−X mL = Y mL <1300, 1600>
120 mL−X mL = Y mL <2000>
NOTE: Y mL indicates the amount of oil in the
refrigerant line, the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the
same times as the compressor, subtract the rated oil
amount of the each part from Y mL and discharge
from the new compressor.
Quantity:
•Evaporator: 60 mL
•Condenser: 15 mL
•Suction hose: 10 mL
•Receiver: 10 mL

COMPRESSOR MAGNETIC CLUTCH
OPERATION CHECK
Connect the compressor connector terminal to the
battery positive (+) terminal and earth the battery’s
negative (−) terminal to the compressor unit. At that
time, the magnetic clutch should make a definite
operating sound.

CAUTION
As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material
to plug the hose and nipples.
To prevent the entry of dust or other foreign bodies,
plug the dismantled hose and condenser assembly
nipples.
INSTALLATION SERVICE POINT
>>A<< CONDENSER INSTALLATION
When replacing the condenser, refill it with a
specified amount of compressor oil and install it. (to
the vehicle).
Compressor oil: SUN PAG 56
Quantity: 15 mL

CONDENSER FAN MOTOR CHECK
Check to be sure that the condenser fan motor
operates when battery voltage is applied to terminal
2 and terminal 1 earthed.
