Hayden 2722 Engine Cooling Fan Clutch

Hayden 2722 Fan Clutch Overview

The Hayden Fan Clutch 2722 is a standard-duty thermal engine cooling fan clutch built for reverse-rotation applications. It uses an aluminum construction, a flange mount, and a 4-bolt pattern to match the specified OE-style cooling fan setup on select Chevrolet and GMC vehicles.

Compatible with 1987-1993 Chevrolet S10, 1988-1990 Chevrolet Astro, 1987-1988 Chevrolet S10 Blazer, 1987-1990 GMC S15, 1988-1990 GMC Safari, 1987-1988 GMC S15 Jimmy, and 1991-1993 GMC Sonoma applications with the listed rear-mounted fan and A/C configurations, Hayden 2722 is a direct-fit cooling service part for reverse rotation systems.

Key Features

• Standard-duty thermal fan clutch for engine cooling control
• Reverse rotation design for specified GM applications
• Aluminum body with raw aluminum finish
• Flange mounting style with 4 bolt holes and M10 x 1.5 threaded holes
• 7.2 in. clutch maximum diameter and 3.8 in. overall height
• Performance rated and meets or exceeds OEM requirements

Detailed Description

Hayden 2722 is engineered as a thermal fan clutch for vehicles that use a reverse-rotation cooling fan arrangement. The standard-duty design helps regulate fan engagement based on temperature demand, supporting consistent airflow through the radiator and condenser in A/C-equipped trucks and vans. The flange mount, 4-bolt pattern, 2.43 in. mount diameter, and 3.25 in. fan bolt circle are specified for the listed applications, including Chevrolet S10 and GMC Sonoma fitments. This part cross-references Four Seasons 36977 and Gates 22147 for the same application.

As part of the Hayden Fan Clutch line, this unit is built for OE-style replacement service where correct rotation, mounting geometry, and thermal operation matter. Hayden 2722 is a practical choice when replacing a worn clutch on a Chevrolet S10, GMC S15, or related GM platform with rear-mounted fan and A/C requirements.

What It Helps Address

• Fan clutch slip that reduces cooling fan engagement
• Overheating caused by weak or inconsistent fan drive
• Noisy or rough fan clutch operation
• Cooling performance loss in A/C-equipped vehicles
• Incorrect replacement parts for reverse-rotation fan systems

Installation Notes and Tips

Verify reverse rotation, flange mount style, bolt pattern, and fan bolt circle before installation. Confirm the vehicle uses the listed rear-mounted fan and A/C configuration, and compare the clutch depth, diameter, and mounting dimensions to the original unit. Mounting hardware is not included, so reuse or source the correct hardware as needed. Always inspect the fan blades, water pump area, and surrounding cooling components during replacement.

Quality Assurance

Hayden 2722 is a new, performance-rated fan clutch that meets or exceeds OEM requirements for the specified applications. Its aluminum construction and OE-style dimensions support accurate fitment on compatible Chevrolet and GMC cooling systems.
