Four Seasons 46017 Engine Cooling Fan Clutch

Heavy Duty Thermal Fan Clutch for Colorado and Canyon

Four Seasons Fan Clutch 46017 is a new heavy-duty thermal engine cooling fan clutch built for reverse-rotation applications. It is engineered for Chevrolet Colorado and GMC Canyon models, with additional coverage for select Isuzu i-280 and i-290 applications.

Four Seasons Fan Clutch 46017 uses an aluminum housing, a non-electronic thermal design, and a severe-duty truck fan drive layout to support cooling system performance in demanding service conditions.

Key Features

• Heavy-duty thermal fan clutch for engine cooling control
• Reverse rotation design for listed applications
• Aluminum construction with raw aluminum finish
• Severe duty and truck fan drive type
• Non-electronic clutch design
• Meets or exceeds OEM requirements
• Performance rated for demanding cooling system service

Product Details

This Four Seasons Fan Clutch 46017 is built around a 6.45-inch clutch diameter, 4.63-inch overall height, and 3.25-inch fan bolt circle. It features a hex mounting type, M10 x 1.5 hole thread specification, 1.44-inch mount diameter, and 1.18-inch pilot diameter. The thermal clutch design responds to operating temperature to help regulate fan engagement in the cooling system.

Four Seasons Fan Clutch 46017 is a direct-fit cooling component for 2004-2012 Chevrolet Colorado, 2004-2012 GMC Canyon, 2007-2008 Isuzu i-290, and 2006 Isuzu i-280 applications. This part cross-references Dorman HELP 46017 for the same application.

What It Helps Address

• Cooling fan engagement issues on reverse-rotation systems
• Excessive engine temperature during stop-and-go driving
• Reduced airflow through the radiator and condenser
• Fan clutch wear in heavy-duty truck cooling setups
• Inconsistent thermal response from a failing clutch

Installation Notes and Tips

Verify reverse rotation, bolt pattern, mount diameter, pilot dimensions, and clutch depth before installation. Mounting hardware is not included, so reuse or source the correct hardware separately. Confirm clearance around the fan, shroud, and accessory drive components before final tightening.

Quality Assurance

Four Seasons 46017 is a new, performance-rated fan clutch that meets or exceeds OEM specifications for the listed applications. The heavy-duty thermal design and aluminum construction support consistent cooling-system operation in service conditions where fan control matters.
