Severe Duty Thermal Fan Clutch
The Four Seasons 46034 fan clutch is a thermal, non-electronic engine cooling fan clutch built for severe-duty and truck fan drive applications. It uses an aluminum construction, standard rotation, and a 6-bolt mounting pattern to help maintain consistent fan engagement in demanding cooling systems.
Compatible With truck cooling systems that use a 7.4-inch clutch diameter, 1.88-inch mount diameter, and 6-inch fan bolt circle, this Four Seasons Fan Clutch line is aimed at direct-fit replacement needs where OE-style dimensions matter. The 46034 is a new, performance-rated unit that meets or exceeds OEM requirements.
Key Features
- Four Seasons Fan Clutch line for severe-duty cooling applications
- Thermal, non-electronic design for mechanical fan control
- Aluminum housing with raw aluminum finish
- Standard rotation and HEX mounting type
- 6 bolt holes, 6 mounting holes, and 5/16-18 hole thread
- 7.4-inch clutch diameter with 4.39-inch overall height
- Meets or exceeds OEM specifications
- New, performance-rated replacement part
Product Details
Four Seasons part number 46034 is engineered as a severe-duty truck fan drive clutch for cooling systems that rely on thermal engagement rather than electronic control. The clutch features a 2.07-inch distance from clutch to mounting flange, 0.58-inch pilot depth, and 1.18-inch pilot diameter for dimensional accuracy during replacement. This part cross-references Dorman HELP 46034 for the same application.
What It Helps Address
- Engine overheating caused by weak fan clutch engagement
- Reduced airflow at idle or low road speed
- Fan noise from a worn thermal clutch
- Cooling performance loss in severe-duty truck use
- Fitment issues when replacing an OE-style 6-bolt fan clutch
Installation Notes
Verify clutch diameter, bolt circle, pilot dimensions, rotation, and mounting style before installation. Mounting hardware is not included, so reuse or source the correct hardware separately if required by the vehicle. Confirm the fan and water pump interface matches the 6-bolt, HEX-mount configuration before final assembly.
Quality Assurance
The Four Seasons 46034 is a new replacement fan clutch that meets or exceeds OEM specifications and is performance rated for severe-duty service. Four Seasons Fan Clutch products are built for direct replacement use in demanding cooling applications, including truck-oriented systems such as Ford F-150 and Chevrolet Silverado cooling setups when the listed dimensions and mounting style match.
