Product Details

Hayden Fan Clutch 2657 is a thermal engine cooling fan clutch designed for standard-duty cooling applications where consistent fan engagement is needed as engine temperature rises. The aluminum housing, 6.65-inch clutch diameter, 3.02-inch overall height, and 2.44-inch distance from clutch to mounting flange support OE-style fitment on the listed Toyota and Isuzu vehicles. This part number 2657 is a direct replacement option for service work on older import cooling systems, including Toyota 4Runner, Pickup, T100, and Land Cruiser models.

This part cross-references Four Seasons 36925 and Gates 22076 for the same application.

What It Helps Address

• Engine overheating caused by a worn or weak fan clutch
• Delayed fan engagement during hot idle or low-speed driving
• Cooling fan noise from a failing thermal clutch
• Reduced airflow through the radiator and condenser
• Cooling system performance loss on Toyota and Isuzu applications

Installation Notes and Tips

Verify the flange mount, 4-bolt pattern, M6 x 1.0 hole thread, 5.35-inch fan bolt circle, and standard rotation before installation. Confirm pilot dimensions and overall height against the original unit to ensure proper clearance. Mounting hardware is not included, so reuse or source the correct hardware separately as needed. Always inspect the fan blade, water pump, and surrounding cooling components during replacement.
