Hayden 2693 Engine Cooling Fan Clutch

Hayden 2693 Fan Clutch Overview

Hayden 2693 is a standard-duty thermal fan clutch built for reverse rotation cooling systems. With an aluminum body, flange mounting, and a 6.3-inch maximum diameter, it is a direct-fit cooling component for select Mercedes-Benz applications, including Mercedes-Benz 300D, 300E, 300SD, 300TD, 300SE, 300SEL, 300SL, 300SDL, S320, E320, and SL320.

The Hayden Fan Clutch line focuses on OE-style cooling control for import vehicles, and part number 2693 follows that approach with a non-electronic thermal design and performance-rated construction.

Key Features

• Reverse rotation design for listed Mercedes-Benz applications
• Standard-duty construction with aluminum material
• Flange mounting with 3 mounting holes and 4-bolt pattern
• 6.3-inch clutch diameter and 5.79-inch fan bolt circle
• Meets or exceeds OEM requirements
• New, performance-rated replacement part
• Raw aluminum finish

Detailed Description

Hayden 2693 fan clutch is engineered for vehicles that use a reverse rotation thermal clutch to regulate airflow through the radiator. It uses a standard-duty thermal response to engage the fan as engine temperature rises, helping maintain consistent cooling performance in daily driving and stop-and-go conditions. The aluminum housing, flange mount, and compact 1.63-inch overall height support a direct replacement fit on the specified Mercedes-Benz cooling system applications. This part number 2693 is listed for multiple Mercedes-Benz models, including 1994-1999 Mercedes-Benz S320, 1996-1997 Mercedes-Benz E320, and 1994-1997 Mercedes-Benz SL320, along with earlier 300-series applications.

This part cross-references Dorman - HELP 46008 for the same application.

What It Helps Address

• Engine overheating caused by a worn or weak fan clutch
• Delayed fan engagement in thermal cooling systems
• Cooling fan noise from a failing clutch mechanism
• Reduced airflow at idle or low vehicle speed
• Cooling performance issues on reverse rotation Mercedes-Benz applications

Installation Notes and Tips

Verify the reverse rotation design, flange mount style, bolt pattern, and fan bolt circle before installation. Confirm the clutch diameter, pilot diameter, and mounting dimensions against the original part on the vehicle. This Hayden 2693 fan clutch is listed for Mercedes-Benz 300D, 300E, 300SD, 300TD, 300SE, 300SEL, 300SL, 300SDL, S320, E320, and SL320 applications, so matching the exact engine cooling setup is important for proper fitment. Mounting hardware is not included.

Quality Assurance

Hayden lists this fan clutch as a new, performance-rated replacement that meets or exceeds OEM requirements. The thermal, standard-duty design is intended to provide consistent cooling control for the specified Mercedes-Benz fitments.
