Hayden 3241 Engine Cooling Fan Clutch

Hayden 3241 Fan Clutch Overview

The Hayden 3241 engine cooling fan clutch is an electronic, electro-viscous severe duty unit built for controlled fan engagement under demanding heat loads. It is designed for 2015-2019 Ford F-250 Super Duty and Ford F-350 Super Duty applications where consistent cooling performance matters.

Backed by Hayden’s 45+ years of automotive cooling experience, the Fan Clutch line focuses on durable thermal management for trucks that work hard in high-load conditions. The Hayden 3241 is a direct-fit style replacement for severe duty cooling systems that use a 4-bolt, 4-mount-hole electronic clutch design.

Detailed Product Description

The Hayden 3241 fan clutch is engineered for electronic thermal control in heavy-duty truck cooling systems. With an overall diameter of 9.39 inches (238.5 mm) and a severe duty electro-viscous duty rating, it is built to manage fan engagement based on operating conditions rather than constant mechanical drag. This helps maintain proper engine cooling performance in Ford F-250 Super Duty and Ford F-350 Super Duty models from 2015 through 2019.

This part cross-references Four Seasons 46147 and Gates 22340 for the same application. The Hayden 3241 also aligns with OE-style replacement numbers used in the same cooling system family, making it a practical service part when replacing a worn or failing electronic fan clutch.

Common Problems This Part Can Address

• Cooling fan engagement that is inconsistent or delayed
• Excessive engine temperature under load or in stop-and-go driving
• Fan clutch noise caused by wear in the electronic clutch assembly
• Reduced cooling performance in severe duty truck use
• Cooling system service needs on Ford Super Duty diesel or gas truck applications with electronic fan clutch control

Installation Notes and Tips

Verify the bolt pattern, mounting hole count, fan bolt circle, and overall diameter before installation. Confirm the vehicle uses an electronic, electro-viscous severe duty fan clutch with the same 4-bolt configuration and M6x1.000 thread specification. For Ford F-250 Super Duty and Ford F-350 Super Duty service, compare the original unit to the Hayden 3241 part number before removal to ensure proper match.

Because this is an engine cooling component, inspect the fan assembly, surrounding hardware, and cooling system condition during replacement. Proper fitment is especially important on 2015-2019 Ford F-250 Super Duty and Ford F-350 Super Duty trucks where cooling demand can be high.

Quality Assurance

Hayden designs and tests its cooling products to handle elevated heat and demanding operating conditions. The Fan Clutch line is supported by more than 45 years of automotive cooling experience, and the Hayden 3241 is built as a severe duty electronic replacement for the specified Ford Super Duty applications.
