Product Details

Hayden Fan Clutch 2691 is engineered for import applications that use a thermal clutch to regulate engine-driven fan speed based on temperature. The 6.3-inch clutch diameter, 1.25-inch mount diameter, and 5.79-inch fan bolt circle support proper fitment on listed BMW models. This unit is a new, standard-duty replacement for vehicles such as the BMW 325Ci, 330Ci, 525i, 530i, and X5, as well as select 3 Series, 5 Series, and Z3 applications.

This part cross-references Four Seasons 36706 and Gates 22099 for the same application. Hayden 2691 is a practical choice when replacing a worn thermal fan clutch on BMW cooling systems that depend on mechanical fan engagement.

What It Helps Fix

• Fan clutch slip that reduces cooling fan engagement
• Engine overheating caused by weak thermal response
• Excessive fan noise from a failing clutch assembly
• Inconsistent cooling performance at idle or low speed
• Cooling system wear related to an aging mechanical fan clutch

Installation Notes

Verify the fan bolt circle, mount diameter, pilot dimensions, and rotation before installation. This Hayden 2691 clutch uses a 3-bolt mounting pattern with M6 x 1.0 hole threads and does not include mounting hardware. Confirm the vehicle’s existing fan clutch style matches the listed thermal, standard-duty import configuration before service.
