Compressor Clutch: Procedures
A/C Clutch Plate Inspection
A/C CLUTCH PLATE INSPECTION
NOTE: The A/C clutch can be serviced in the vehicle. The refrigerant system can remain fully-charged during compressor clutch, pulley and
bearing assembly, or coil replacement.
Examine the friction surfaces of the pulley and the clutch plate (2) for wear. The pulley and clutch plate should be replaced if there is excessive wear or
scoring.
If the friction surfaces are oily, inspect the shaft and nose area of the A/C compressor (1) for refrigerant oil. If refrigerant oil is found, the compressor
shaft seal is leaking and the A/C compressor must be replaced.
Check the pulley bearing for roughness or excessive leakage of grease. Replace the pulley and bearing assembly, if required.
A/C Clutch Break-In
A/C CLUTCH BREAK-IN
After a new A/C compressor clutch has been installed, cycle the compressor clutch approximately 20 times (5 seconds on, then 5 seconds off). During
this procedure, set the A/C-heater controls to the A/C Recirculation Mode, the blower motor in the highest speed position, and the engine speed at 1500
to 2000 rpm. This procedure (burnishing) will seat the opposing friction surfaces and provide a higher compressor clutch torque capability.
