Hayden 1706 Engine Cooling Fan Clutch

Hayden 1706 Fan Clutch Overview

The Hayden 1706 is a non-thermal engine cooling fan clutch built for standard-duty cooling systems that use standard or reverse rotation. With an aluminum body, flange mounting, and a 7.2-inch maximum diameter, it serves as a direct replacement for a wide range of classic Dodge, Chevrolet, GMC, Jeep, Chrysler, and Cadillac applications.

Hayden Fan Clutch products are built for cooling-system service where consistent mechanical fan engagement is required without electronic control. The 1706 follows that approach with a non-electronic, non-thermal design for vehicles that rely on fixed operating characteristics rather than temperature-actuated modulation.

Product Details

The Hayden 1706 fan clutch is a B-type non-thermal unit with a 7.2-inch clutch diameter, 3.33-inch overall height, and 1.75-inch distance from clutch to mounting flange. It uses a 5/16-18 hole thread pattern and a 0.63-inch pilot diameter with a 1.03-inch pilot depth. This makes it a practical replacement for older belt-driven cooling systems that need a standard mechanical fan clutch rather than an electronic or thermal-controlled unit.

Compatible With long-tail search needs such as Dodge D150 fan clutch replacement, Chevrolet G20 non-thermal fan clutch, and Jeep J10 standard rotation cooling fan clutch. It also matches applications across Dodge B150, B250, B350, W150, W250, Ramcharger, Dakota, and similar vintage truck and van platforms. This part cross-references Monroe Shocks & Struts (e.g., 271341) for the same application.

Common Cooling Issues It Can Address

• Fan clutch wear that reduces mechanical fan engagement
• Cooling fan noise caused by a failing clutch assembly
• Overheating concerns in belt-driven cooling systems
• Inconsistent fan drive performance on standard-rotation setups
• Replacement needs for non-thermal fan clutch applications

Installation Notes and Tips

• Verify standard or reverse rotation before installation.
• Confirm flange mounting, bolt circle, pilot diameter, and overall height against the original unit.
• Mounting hardware is not included.
• Check fan and pulley clearance before final tightening.
• Use the vehicle’s original cooling-system configuration to confirm fitment, especially on applications noted without AC or with specific axle-ratio requirements.

Quality Assurance

The Hayden 1706 is a new replacement fan clutch that meets or exceeds OEM specifications and is performance rated for service use. Its aluminum construction and standard-duty design support dependable cooling-system replacement across confirmed fitments including Dodge D150, Chevrolet G10, and Jeep Wagoneer applications.
