Bolt Removal/Installation Note

1. When removing or installing the bolt, hold the 

pressure plate in place as shown in the figure.

2. When installing a new A/C compressor body, 

replace the bolt.

Stator and Thermal Protector Removal Note

1. After removing the stator and thermal protector, completely remove the silicone adhering to the A/C 

compressor side.

Stator and Thermal Protector Installation Note

1. Apply approximately 1 g {0.04 oz} of silicone 

(Shin-Etsu Silicone KE-347W or similar) to the 
contact surface of the thermal protector, then 
thoroughly install it onto the A/C compressor, 
leaving no gaps.

Screw Installation Note

1. When installing a new stator and thermal protector, replace the screw.

Clamp Installation Note

1. When installing a new stator and thermal protector, replace the clamp.

Snap Ring Installation Note

1. When installing a new pressure plate, A/C 

compressor pulley, stator, or A/C compressor 
body, replace the snap ring.

MAGNETIC CLUTCH ADJUSTMENT

A6E854061010W02

1. Measure the clearance around the entire 

circumference between the pressure plate and A/
C compressor pulley using a thickness gauge.

2. Verify that the clearance is within the 

specification.

• If not within the specification, remove the 

pressure plate and adjust the clearance by 
changing the shim (0.2 mm {0.008 in}, 0.5 
mm {0.02 in}) or the number of shims.

Clearance

0.3—0.5 mm {0.012—0.019 in}

MAGNETIC CLUTCH INSPECTION

A6E854061010W03

1. Connect battery positive voltage to terminal A of 

magnetic clutch and ground to A/C compressor 
body.

2. Verify that the magnetic clutch operates.

• If not as specified, replace the stator and 

thermal protector.

SOLAR RADIATION SENSOR INSPECTION

A6E854061751W02

1. Shine an incandescent light (60 W) on the solar radiation sensor from a distance of approximately 100 mm 

{3.94 in}.

2. Connect positive (+) lead to terminal A and 

negative (

−) lead to terminal B of the solar 

radiation sensor.

• If the output voltage is not above 0.45 V, 

replace the solar radiation sensor.
