There could be some confusion on 2.9ls depending on what Fan Belts are used, V-belt or serpentine belt
95% of engines have the crankshafts spinning clockwise if standing in FRONT of the engine
So on V-belt engines all the pullies will spin clockwise
So a Fan clutch nut could unscrew if it was regular threads
Get a bolt hold the head in left hand but the END of bolt facing you, turn the bolt head Counter-Clockwise so the END is turning clockwise, if there was a nut on the bolt it would unscrew
With serpentine belts the crank pulley is ribbed, so any ribbed pullies will also spin clockwise
But some pullies are smooth, in contact with back(smooth)side of serpentine belt, and these spin counter-clockwise
So if the water pump pulley is smooth fan clutch nut will use regular threads
If its ribbed then reverse threads
