Product Details

Hayden Fan Clutch 2744 is a C-style heavy-duty thermal fan clutch engineered for vehicles that rely on reverse-rotation fan operation. The aluminum housing helps keep weight down while maintaining the strength needed for truck and van cooling systems. Its 1.18-inch pilot diameter, 1.44-inch mount diameter, and 3.25-inch fan bolt circle support proper alignment in the specified applications. This part cross-references Four Seasons 4820R and Gates 22157 for the same application.

Hayden 2744 is also used in several heavy-duty tow package and optional thermal fan clutch applications, including reverse-rotation setups found on GM trucks and vans.

Common Cooling Problems It Can Address

• Fan clutch that no longer engages at the proper temperature
• Reduced airflow at idle or low road speed
• Cooling system strain during towing or heavy hauling
• Excessive fan noise from a worn thermal clutch
• Overheating concerns in stop-and-go driving

Installation Notes and Tips

Verify reverse rotation, pilot dimensions, bolt circle, and mounting style before installation. Mounting hardware is not included, so reuse or source the correct hardware separately if needed. Confirm the vehicle’s cooling package, tow package, AC configuration, and axle ratio notes against the fitment list before ordering. For best results, inspect the fan blade, water pump, and surrounding cooling components during replacement.
