Product Details

The Hayden 2834 fan clutch is engineered as a severe-duty cooling component for vehicles that rely on mechanical fan control rather than electronic actuation. Its thermal operation responds to temperature changes to regulate fan engagement, helping maintain airflow through the radiator and cooling stack when engine demand increases. The aluminum body, 1.2-inch distance from clutch to mounting flange, 1.18-inch pilot diameter, and 0.67-inch pilot depth support a precise mechanical fit in the correct application. This part cross-references Four Seasons (e.g., 36749, 77309) for the same application.

What It Helps Address

• Engine temperature rise during towing or heavy-load operation
• Reduced fan engagement in severe-duty cooling systems
• Cooling performance loss from a worn thermal fan clutch
• Noise or inconsistency caused by a failing mechanical clutch
• Fitment issues when replacing an OEM-style truck fan drive clutch

Installation Notes and Tips

Verify the fan bolt circle, mount diameter, pilot dimensions, rotation, and overall height before installation. Mounting hardware is not included, so reuse or source the correct hardware separately as needed. Confirm the vehicle uses a thermal, non-electronic fan clutch with the specified 6-bolt pattern and severe-duty configuration before ordering. Fits 2006-2011 Honda Civic, front right is not applicable here; use the vehicle-specific cooling system dimensions and OE reference numbers to confirm the correct application for your truck or heavy-duty platform. Search terms such as Hayden 2834 fan clutch, severe duty fan clutch, and truck fan drive replacement are commonly used for this type of part.

Hayden identifies this fan clutch as meeting or exceeding OEM specifications and performance rated for severe-duty service. The new aluminum construction and thermal design support replacement of a worn mechanical fan clutch in the correct application. For buyers comparing Hayden 2834 against OE references, this part is positioned as an OE-style cooling replacement for demanding truck use.
