Common Cooling System Issues

• Fan clutch that stays engaged too long or does not engage at the proper temperature
• Excessive fan noise from a worn thermal clutch
• Reduced radiator airflow at idle or low road speed
• Cooling system temperature fluctuation during stop-and-go driving
• Replacement need after clutch bearing or internal fluid wear

Installation Notes

Verify the fan bolt circle, mounting flange, pilot dimensions, and rotation before installation. This part uses an M6 x 1.0 hole thread pattern and a 4-bolt flange mount, so matching the original fan clutch configuration is important for proper alignment and operation. Confirm clearance around the radiator, shroud, and fan blades during service.
