• Noise or irregular operation from a worn fan clutch
• Temperature control issues in severe-duty driving

Installation Notes and Tips

Verify reverse rotation, mounting style, pilot dimensions, and bolt pattern before installation. Mounting hardware is not included, so reuse or source the correct hardware separately if required by the vehicle. Confirm clearance around the 7.4-inch clutch diameter and overall height before final assembly.
