Detailed Product Description

The Hayden 2560 fan clutch is engineered for vehicles that use a thermal, mechanically driven cooling fan. Its standard rotation, 3 in. mount diameter, 0.63 in. pilot diameter, and 1.94 in. distance from clutch to mounting flange help support proper fitment in the intended cooling fan assembly. This part number 2560 is a practical replacement choice for drivers servicing older Nissan and Infiniti cooling systems where consistent fan engagement is needed to manage engine temperature.

What It Helps Address

• Fan engagement that is delayed, inconsistent, or noisy
• Reduced cooling performance at idle or low vehicle speed
• Mechanical fan systems that need an OE-style replacement clutch
• Cooling system service on older Nissan and Infiniti models

Installation Notes and Tips

Verify the fan bolt circle, mounting flange style, pilot dimensions, and rotation before installation. This Hayden 2560 uses a 4-bolt flange mount and does not include mounting hardware. Confirm the existing fan clutch matches the thermal, standard-duty configuration used on the vehicle before replacing the part.

Quality Assurance

Hayden lists this fan clutch as meeting or exceeding OEM requirements and rates it for performance use. The aluminum construction and thermal design support dependable cooling-system service for the specified Nissan and Infiniti applications.
