ok, throw the serpent belt today it snapped two bolts on the fan hub behind the fan clutch, took whole fan assembly away from engine,so how do you take the fan away from the clutch, when i try to turn the big nut on the fan it turns the fan.

 

nut is reverse thread. Turns clock wise to take off. I use a air hammer on edge of nut to loosen, then used BIG channel lock on front of pulley to hold it still then used big wrench to break it loose.
