GMB 947-2090 Engine Cooling Fan Clutch

The GMB 947-2090 is a thermal engine cooling fan clutch built to meet or exceed OEM specifications. It uses an aluminum construction and OEM-standard grading to support consistent cooling fan engagement on select Mercedes-Benz applications, including Mercedes-Benz ML500, ML55 AMG, E430, SL500, SL55 AMG, ML430, and E420 models.

Key Features

• Thermal fan clutch for temperature-based fan engagement
• OEM Standard item grade for OE-style fit and function
• Aluminum construction for durable cooling system service
• New replacement part for maintenance and repair
• Engine cooling fan clutch for reverse-rotation applications
• Part number 947-2090 for easy identification

Detailed Description

This GMB engine cooling fan clutch is engineered for Mercedes-Benz cooling system service where a thermal clutch is required. It is designed for counter clockwise, reverse rotation applications and is listed for 1997-2006 Mercedes-Benz vehicles, including 2002-2006 Mercedes-Benz ML500, 2000-2003 Mercedes-Benz ML55 AMG, and 2000-2002 Mercedes-Benz E430 and SL500. The 947-2090 fan clutch helps maintain proper fan operation by responding to temperature changes rather than running at a fixed rate.

This part cross-references Four Seasons 46058 and Hayden 2685 for the same application. If you are replacing a worn Mercedes-Benz ML430 fan clutch or sourcing a thermal fan clutch for a Mercedes-Benz SL55 AMG, this GMB 947-2090 offers an OE-style replacement path with the correct reverse-rotation configuration.

What It Helps Address

• Fan clutch slip that can reduce cooling fan performance
• Overheating caused by inconsistent fan engagement
• Noisy or worn cooling fan clutch operation
• Cooling system performance loss on reverse-rotation Mercedes-Benz applications
• Replacement needs for aging thermal fan clutch assemblies

Installation Notes and Tips

Verify the vehicle’s rotation direction and application before installation. This part is listed for counter clockwise, reverse rotation use, so matching the original clutch specification is important for proper operation. Confirm fitment by year, model, and cooling fan configuration on Mercedes-Benz ML500, ML55 AMG, E430, SL500, SL55 AMG, ML430, and E420 vehicles before replacing the existing unit.

Quality Assurance

GMB states that this part is manufactured to meet or exceed OEM specifications. The 947-2090 is a new, OEM Standard thermal fan clutch built for direct replacement service in supported Mercedes-Benz cooling systems.
