Product Details

The Hayden Fan Clutch 2871 is engineered as a severe-duty thermal clutch for engine cooling systems that rely on mechanical fan engagement. Its aluminum body, 7.4-inch overall diameter, 3.53-inch overall height, and 1.2-inch to 1.21-inch distance from clutch to mounting flange provide the dimensional profile needed for proper fitment in supported applications. The 1.18-inch pilot diameter, 0.67-inch pilot depth, and 48 mm mount diameter are important reference points when matching this part to the original unit. This part cross-references Dorman - HELP 46038 for the same application.

For drivers and technicians searching for a Hayden 2871 fan clutch for truck cooling repair, this part is intended for systems that require a thermal clutch with standard rotation and a 5/16-18 hole thread pattern. It is a new replacement part and does not include mounting hardware.

What It Helps Address

• Engine overheating caused by a worn fan clutch
• Delayed fan engagement in thermal cooling systems
• Excessive fan slip under load
• Cooling performance loss in severe-duty service
• Noisy or inconsistent mechanical fan operation

Installation Notes

Verify the fan bolt circle, pilot diameter, mount diameter, rotation, and overall height against the original fan clutch before installation. Confirm that the vehicle uses a thermal, non-electronic clutch with a 6-bolt pattern and standard rotation. This Hayden fan clutch 2871 is commonly searched for truck cooling repair and OE-style replacement work on supported make/model applications, including vehicle-specific fitment checks for make/model keywords such as Ford F-150 and Chevrolet Silverado where applicable to the exact cooling setup.

Mounting hardware is not included, so reuse or source the correct hardware separately if required by the application. Always inspect the fan, water pump area, and surrounding cooling components before installing the new clutch.

Quality Assurance

Hayden identifies this fan clutch as meeting or exceeding OEM requirements and performance rated for severe-duty use. The 2871 is a new thermal fan clutch built to match the dimensional and functional requirements of supported cooling systems.
