Product Details

Hayden Fan Clutch part number 2651 is engineered as an A - 5" & 6" import-style thermal clutch for vehicles that use a flange-mounted cooling fan assembly. The 3-inch mount diameter, 0.67-inch pilot diameter, and 0.45-inch pilot depth help define the fitment profile for the cooling fan interface. This part cross-references Monroe Shocks & Struts (e.g., 5580) for the same application.

Fits 1989-1991 Mazda MPV, N/A. For Mazda MPV cooling system service, this fan clutch helps restore proper fan engagement behavior when the original unit no longer responds correctly to temperature changes.

Common Problems It Can Help Address

  • Engine cooling fan that stays engaged too long or not long enough
  • Excessive fan noise from a worn thermal clutch
  • Cooling performance loss during idle or low-speed driving
  • Temperature fluctuation caused by inconsistent fan drive
  • Replacement need for a damaged or fatigued fan clutch assembly

Installation Notes and Tips

Verify the fan bolt circle, mount diameter, pilot dimensions, and standard rotation before installation. This Hayden 2651 uses a flange mount and M6 x 1.0 hole thread specification, and mounting hardware is not included. Confirm vehicle application by VIN when servicing 1989-1991 Mazda MPV models, especially where notes specify fitment up to VIN No. 350466.

Quality Assurance

Hayden designs this fan clutch to meet or exceed OEM requirements for standard-duty thermal cooling applications. The aluminum construction and OE-style fitment profile support dependable replacement service for the Mazda MPV cooling system.
