What It Helps Address

Installation Notes and Tips

Verify standard rotation, bolt pattern, mount diameter, and pilot depth before installation. This fan clutch uses a 4-bolt, hex-mount design and does not include mounting hardware. Confirm clearance around the fan assembly and inspect the fan blades, water pump, and related cooling components during replacement. Use the vehicle-specific fitment notes to match severe duty thermal fan clutch applications on 2021-2024 Ram 1500 and Ram 1500 Classic, as well as earlier Ram and Dodge Ram models listed for standard rotation service.
