turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are right hand. A Snap-On 36 MM Fan Wrench
(number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) can be used. Place a bar or screwdriver between water pump pulley
bolts to prevent pulley from rotating. Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
6. If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
7. Remove fan shroud attaching hardware (two bolts at bottom-two clips at top).

9. After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone
fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.
