The reason the fan clutch is LEFT hand threads is so it won't come off. Any kind of thread locker will make removal MUCH more difficult the next time.
My '85 Factory Service Manual (Engine)(6.9) says nothing about thread locker for re installation of the fan clutch assembly onto the water pump. 30 ft lb.
The last time I changed the water pump on my 6.9 there was NO thread locker on the large left hand nut and it came loose with a hard bump with my home made giant wrench (1 7/8")--- normal right hand tighten direction.

I did not use thread locker on re assembly.
