Hayden 6250 Engine Cooling Fan Clutch

Hayden 6250 Fan Clutch Overview

The Hayden 6250 is a thermal engine cooling fan clutch built for standard-duty operation in select Audi applications. It uses an aluminum construction, a reverse rotation design, and a hex mounting type to match the specified OE-style setup for proper fan engagement and cooling control.

For Audi A6 Quattro, Audi A8, Audi A8 Quattro, Audi S6, and Audi S8 applications, this Hayden Fan Clutch line part number 6250 is a direct-fit cooling service component for vehicles that use a 5" and 6" import-style clutch configuration.

Product Details

This Hayden 6250 fan clutch is engineered as a thermal replacement for import cooling systems that rely on temperature-based fan engagement. The aluminum housing, 160 mm overall diameter, and 55.1 mm overall height support a compact OE-style fit, while the M6 x 1.0 threaded hole pattern and 147.1 mm fan bolt circle align with the listed application requirements. This part cross-references Four Seasons 46082 and Gates 22316 for the same application.

Compatible With 2000-2004 Audi A6 Quattro, 2004 Audi S6, 2001 Audi S6, 1997-2003 Audi A8 Quattro, 2002-2003 Audi S6, 2001-2003 Audi S8, and 1997-2000 Audi A8. The Hayden 6250 is a practical choice when replacing a worn thermal fan clutch on Audi cooling systems that require reverse rotation operation.

Common Cooling Issues It Can Address

• Fan clutch that no longer engages at the correct temperature
• Cooling fan noise caused by a worn clutch mechanism
• Reduced airflow through the radiator at idle or low speed
• Overheating concerns tied to inconsistent fan drive
• Cooling performance loss from a damaged or fatigued clutch assembly

Installation Notes and Tips

Verify reverse rotation, bolt circle, mount diameter, and pilot depth before installation. Confirm the vehicle uses the listed 5" and 6" import-style thermal clutch configuration and match the 3-bolt mounting pattern to the existing fan assembly. Mounting hardware is not included, so reuse or source the correct hardware separately as needed. Always inspect the fan blades, water pump area, and surrounding cooling components during replacement.

Quality Assurance

Hayden designs this fan clutch to meet or exceed OEM specifications and rates it for performance use. As a new standard-duty thermal replacement, the Hayden 6250 is built to support consistent cooling-system service on the listed Audi applications.
