How do you remove the fan clutch on a 2000 GMC safari?

To remove the fan clutch on a 2000 GMC Safari, first ensure the engine is cool and disconnect the negative battery terminal. Next, remove the fan shroud for better access, then use a wrench to hold the water pump pulley in place while you unscrew the fan clutch from the water pump. If the clutch is stubborn, you may need a fan clutch tool or a strap wrench. Once loose, it can be unscrewed and removed along with the fan.
