Product Details

Hayden Fan Clutch 2794 is engineered for vehicles that rely on a thermal fan clutch to regulate airflow through the radiator and cooling stack. The severe duty design is suited to Ford Ranger and Ford Explorer platforms, along with Mazda B4000 and Mazda Navajo applications that specify reverse rotation. Its aluminum body, OEM-matching dimensions, and thermal operation support proper fan engagement in demanding cooling conditions.

This part number is a direct replacement option for a wide range of late-model and earlier Ford and Mazda applications, including 1990-2011 Ford Ranger, 1991-2001 Ford Explorer, 2001-2005 Ford Explorer Sport Trac, 1998-2010 Mercury Mountaineer, 1994-1997 Mazda B4000, and 1991-1994 Mazda Navajo listings shown in the fitment data. Hayden 2794 is built for applications that require a reverse-rotation severe duty thermal engine cooling fan clutch.

Common Cooling Issues This Part Addresses

• Fan clutch engagement that no longer responds correctly to temperature changes
• Reduced airflow through the radiator at idle or low vehicle speed
• Cooling system strain during towing, hauling, or stop-and-go driving
• Noise or inconsistency from a worn mechanical fan clutch
• Fitment problems caused by incorrect rotation or mounting dimensions

Installation Notes and Tips

Verify reverse rotation, bolt pattern, pilot dimensions, and fan bolt circle before installation. This clutch uses a 4-bolt mounting pattern with M6 x 1.0 hole threads, and mounting hardware is not included. Confirm the vehicle’s cooling system calls for a thermal, non-electronic fan clutch and match the application notes for year, make, and model before final assembly.
