Detailed Description

Four Seasons 46029 is an engine cooling fan clutch designed for standard rotation thermal operation in select Toyota trucks and SUVs. The aluminum body, 4-hole flange mount, and import-style clutch profile support direct replacement service where the original clutch uses a 5" or 6" configuration. With a 2.98 in. distance from clutch to mounting flange and a 0.91 in. pilot depth, this unit is built around the dimensional requirements commonly found in Toyota Tacoma, Toyota Tundra, Toyota 4Runner, and Toyota FJ Cruiser cooling assemblies. If you are searching for a Toyota Tacoma fan clutch replacement, Toyota Tundra cooling fan clutch, or Toyota 4Runner thermal fan clutch, Four Seasons 46029 is the matching service part to review.

This part cross-references Dorman HELP 46029 and Gates 22407 for the same application. The Four Seasons 46029 part number also appears in interchange listings for related OE and aftermarket references, making it easier to verify the correct cooling fan clutch before installation.

What It Helps Address

• Cooling fan engagement that is inconsistent or delayed
• Excessive engine temperature during idle or low-speed driving
• Fan clutch noise caused by worn internal thermal components
• Reduced airflow through the radiator and condenser
• Cooling system performance loss on Toyota Tacoma, Tundra, 4Runner, and FJ Cruiser models

Installation Notes and Tips

Confirm the fan bolt circle, mount diameter, pilot depth, and overall height against the original unit before installation. This clutch uses M6 x 1.0 hole threading and a 4-bolt flange pattern, and mounting hardware is not included. Verify standard rotation and thermal clutch type match the vehicle’s original cooling fan clutch specification. For Toyota Tacoma, Toyota Tundra, Toyota 4Runner, and Toyota FJ Cruiser service, compare the original clutch dimensions and mounting style to avoid fitment errors.
