Wrangler L6-4.0L VIN S (2000)
Clutch Break-In
After a new compressor clutch has been installed, cycle the compressor clutch approximately twenty times (five seconds on, then five seconds
off). During this procedure, set the heater-A/C control in the Recirculation Mode, the A/C button in the ON position, the blower motor switch 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.
