INSTALLATION
1. INSTALL COMPRESSOR
(a) Install the compressor with 3 bolts.
Torque: 49 N´m (500 kgf´cm, 36 ft´lbf)
(b) Connect the connector.
2. INSTALL FRONT DRIVE SHAFT LH
(See page SA-33)
3. CONNECT DISCHARGE AND SUCTION HOSES
(a) Lubricate 2 new O-rings with compressor oil and install
them to the hoses.
(b) Connect the both hoses with 2 bolts.
Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
NOTICE:
Hose should be connected immediately after the caps have
been removed.
4. INSTALL AND CHECK DRIVE BELT
(See page AC-17 and AC-15)
5. CONNECT NEGATIVE (-) TERMINAL CABLE TO BAT-
TERY
6. EVACUATE AIR FROM REFRIGERATION SYSTEM
AND CHARGE SYSTEM WITH REFRIGERANT
Specified amount: 1,050 ± 50 g (37.03 ± 1.76 oz.)
7. INSPECT FOR LEAKAGE OF REFRIGERANT
Using a gas leak detector, check for leaks of the refrigerant.
If there is a leakage, check the tightening torque at the joints.
8. INSPECT A/C OPERATION

COMPRESSOR AND MAGNETIC
CLUTCH
ON-VEHICLE INSPECTION
1. INSPECT COMPRESSOR FOR METALLIC SOUND
Check there is abnormal metallic sound from the compressor
when the A/C switch is ON.
If abnormal metallic sound is heard, replace the compressor as-
sembly.
2. INSPECT REFRIGERANT PRESSURE
(See page AC-3)
3. INSPECT VISUALLY FOR LEAKAGE OF REFRIGER-
ANT
Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the compressor assembly.
4. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure resistance between terminal 1 and 2.
Standard resistance:
570 - 1,050 W at 20°C (68 °F)
If resistance is not as specified, replace the compressor.
5. CHECK FOR LEAKAGE OF GREASE FROM CLUTCH
BEARING
6. CHECK FOR SIGNS OF OIL ON PRESSURE PLATE OR
ROTOR
7. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start engine.
(b) Check for abnormal noise from the compressor when the
A/C switch is OFF.
If abnormal noise is being emitted, replace the rotor of magnetic
clutch.
8. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
3 and the negative (-) lead to the body ground.
(c) Check that the magnetic clutch is energized.
If operation is not as specified, replace the magnetic clutch.

REASSEMBLY
Reassembly is in the reverse of disassembly
(See page AC-63).
AFTER REASSEMBLY, CHECK MAGNETIC CLUTCH
CLEARANCE
(a) Set the dial indicator to the pressure plate of the magnetic
clutch.
(b) Connect the magnetic clutch lead wire to the battery posi-
tive (+) terminal.
(c) Check the clearance between the pressure plate and ro-
tor when connecting the negative (-) terminal to the bat-
tery.
Standard clearance:
0.5 ± 0.15 mm (0.020 ± 0.0059 in.)
If the clearance is not within the standard clearance, adjust the
clearance using shims to obtain the standard clearance.
Shim thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020in.)

ON-VEHICLE INSPECTION
1. INSPECT CONDENSER FINS FOR BLOCKAGE OR DAMAGE
If the fins are clogged, wash them with water and dry with compressed air.
NOTICE:
Be careful not to damage the fins.
If the fins are bent, straighten them with a screwdriver or pliers.
2. INSPECT CONDENSER AND FITTINGS FOR LEAKAGE
Using a gas leak detector, check for leaks of refrigerant.
If there is a leakage, check the tightening torque at the joints.
