ISSUE:
A slipping or overheated air conditioner clutch may be caused by insufficient voltage to the clutch and an improper air gap between the clutch
disc and the pulley.
ACTION:
If service is required, install a new A/C clutch assembly and make sure the proper voltage and air gap are present. Refer to the following
service information.
1.
After the new A/C clutch assembly is installed, make sure the air gap between the clutch disc and the pulley is set at 0.020-0.039 inch.
2.
Make sure the voltage at the A/C clutch coil is not less than 10.5 volts. The voltage must be measured at the A/C clutch coil wires, not the battery.
NOTE:
To improve clutch torque, a new A/C clutch should be burnished by cycling it "On" and "Off" manually thirty (30) times. Each cycle should be
two (2) seconds long, one (1) second "On" and one (1) second "Off". This can be done by connecting and disconnecting a jumper wire across
the clutch cycling pressure switch harness connector.
