FAN CLUTCH SERVICE
Fan Drive Inspection
WARNING
Before performing work on the fan drive,
be sure to follow good shop safety
practices. Turn the vehicle’s ignition off,
apply the vehicle’s parking brake and
block the vehicle’s wheels.
1. Start the vehicle’s engine and build air
pressure in excess of 90 psi (621 kPa).
• Manually engage and disengage the fan
drive by disconnecting and reconnecting
the harness connector from the solenoid
valve.
• Observe the fan and fan drive from a
distance. Look for vibration, fan blade
contact, fan drive slippage and fan drive
operation.
2. Refer to Figure 39 and inspect for air
leaks at the points shown.
• Check for air leaks around the fan drive
while applying air to the fan drive.
• Listen for leaks at the solenoid valve
and in the air hoses and fittings.
• Feel for a leak with a wet finger or by
applying soapy water and looking for
bubbles.
Note: Most fan drive failures are caused by
air leaks.

3. Check the fan drive for discoloration or
any other signs of slipping or overheating,
Figure 40. The fan drive may slip if
incoming air pressure is below 90 psi
(621 kPa) or if an air leak exists inside
the fan drive. Never let a leak remain
unattended.
