A/C Clutch Break-In
After a new A/C compressor clutch has been installed, cycle the
compressor clutch approximately
twenty times (five seconds on, then
five 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.
