NOTICE:
Never use water to clean the evaporator.
(b) Check fitting for cracks or scratches.
If necessary, repair or replace.
2. INSPECT HEATER RADIATOR
Inspect fins for blockage.
If the fins are clogged, clean them with compressed air.
3. INSPECT WATER VALVE SERVOMOTOR CIRCUIT
(See page DI±2361)
4. INSPECT AIR OUTLET SERVOMOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
7 and the negative (±) lead to terminal 8.
(b) Connect the negative (±) lead from the battery to each ter-
minal and check that the shaft rotates at each position, as
shown in the illustration.

ON±VEHICLE INSPECTION
1. SET MANIFOLD GAUGE SET (See page AC±18)
2. START ENGINE
3. INSPECT COMPRESSOR FOR METALLIC SOUND
Check if a metallic sound can be heard from the compressor
when the A/C switch is on.
If a metallic sound cannot be heard, replace the compressor as-
sembly.
4. INSPECT REFRIGERANT PRESSURE
(See page AC±3)
5. STOP ENGINE
6. INSPECT VISUALLY FOR LEAKAGE OF REFRIGER-
ANT FROM SAFETY SEAL
Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the compressor assembly.
7. REMOVE MANIFOLD GAUGE SET
(See page AC±19)
8. CHECK FOR LEAKAGE OF GREASE FROM CLUTCH
BEARING
9. CHECK FOR SIGNS OF OIL ON PRESSURE PLATE
If necessary, repair or replace.
10. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start the engine.
(b) Check if abnormal noise is heard from near the compres-
sor when the A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
11. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
3 and the negative (±) lead to body ground.
(c) Check that the magnetic clutch is energized.
If operation is not as specified, replace the magnetic clutch.
12. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure the resistance between terminals 1 and 2.
Standard resistance:
165 to 205 W at 20°C (68°F)
If resistance is not as specified, replace the compressor.

REASSEMBLY
Reassembly is in the reverse order of disassembly (See
page AC±57).
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 positive (+)
terminal of the battery.
(c) Check the clearance between the pressure plate and ro-
tor when connecting the negative (±) terminal to the bat-
tery.
Standard clearance:
0.35 to 0.50 mm (0.014 to 0.024 in.)
If the clearance is not within the standard range, adjust the
clearance using shims to obtain the standard clearance.
Standard thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020in.)

INSTALLATION
1. INSTALL COMPRESSOR
(a) Install the compressor with the cooler bracket with the 3 bolts and nut.
Torque:
Bolt: 47 N´m (480 kgf´cm, 35 in.´lbf)
Nut: 25 N´m (255 kgf´cm, 18 in.´lbf)
(b) Connect the connector.
2. CONNECT DISCHARGE AND SUCTION HOSES
