How do you remove a fan clutch on a 2001 Ford F-150?

To remove the fan clutch on a 2001 Ford F-150, first, disconnect the negative battery cable and remove the radiator shroud for better access. Use a wrench to hold the water pump pulley in place, then use a fan clutch tool or a large wrench to turn the fan clutch counterclockwise to loosen it. Once it's loose, you can unscrew it completely and remove the fan assembly from the engine. Be cautious of any residual coolant and ensure the engine is cool before starting the process.
