Compressor Clutch: Service and Repair

REMOVAL AND INSTALLATION
After new clutch installation, cycle the A/C clutch 20 times (5 seconds ON and 5 seconds OFF). During this procedure, set the system to the A/C mode, engine rpm at 1500-2000, and high blower speed. This procedure (burnishing) will seat the opposing friction surfaces and provide a higher clutch torque capability.

NOTE: Excessive clutch gap will result in clutch slippage or non-engagement.
