b. Attach the clamp.

3. INSPECT MAGNET CLUTCH CLEARANCE

a. Clamp the cooler compressor in a vise.

b. Set the dial indicator to the magnet clutch hub.

c. Connect the battery positive lead to terminal 3 of the magnet clutch connector and the negative lead

to the ground wire. Turn the magnet clutch on and off and measure the clearance.

Standard clearance:

0.35 to 0.60 mm (0.014 to 0.024 in.)

If the measured value is not within the standard clearance, remove the magnet clutch hub and adjust
the clearance using compressor washers to obtain the standard clearance.

Compressor washer thickness:

0.1 mm (0.004 in.)

0.3 mm (0.012 in.)

0.5 mm (0.020 in.)

NOTE:

Adjustment should be performed with 3 or fewer magnet clutch
washers.

d. Remove the cooler compressor from the vise.

INSTALLATION

1. ADJUST COMPRESSOR OIL

a. When replacing the compressor and magnetic clutch with a new one, gradually discharge the

refrigerant gas from the service valve, and drain the following amount of oil from the new
compressor and magnetic clutch before installation.

Standard:

(Oil capacity inside the new compressor and magnetic clutch: 120 +15 cc (4.1 + 0.51 fl.oz.)) -
(Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be
removed from the new compressor when replacing)

NOTE:



When checking the compressor oil level, follow the A/C
system's precautions.



If a new compressor and magnetic clutch is installed without
removing some oil remaining in the pipes of the vehicle, the oil
amount will be too large. This prevents heat exchange in the

2. INSTALL COOLER COMPRESSOR ASSEMBLY

a. Install the cooler compressor and 2 stud bolts.

Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf)

b. Install the 2 bolts and 2 nuts.

Torque: 24.5 N*m (250 kgf*cm, 18 ft.*lbf)

HINT:

Tighten the bolts in the order shown in the illustration to install the cooler compressor.

3. CONNECT SUCTION HOSE

a. Remove the attached vinyl tape from the hose.

b. Sufficiently apply compressor oil to a new O-ring and the fitting surface of the cooler compressor.

Compressor oil:

ND-OIL 8 or equivalent

c. Install the O-ring on the cooler refrigerant suction hose.

d. Connect the cooler refrigerant suction hose on the cooler compressor with the bolt.

Torque: 9.8 N*m (100 kgf*cm, 87 in.*lbf)

refrigerant cycle and causes refrigerant failure.



If the volume of oil remaining in the removed compressor and
magnetic clutch is too small, check for oil leakage.



Be sure to use ND-OIL 8 or equivalent for compressor oil.
