Are you sure that there is something wrong with the threads? 
Usually when this happens I just retighten the bolt with Locktite on 
it.

You should make sure that you have the wavy washer under the 
bolt head, and torque to 92 lb-ft.

It is also a good idea to check the dowel pin on the pulley to make 
sure it is still good and that its mating hole in the fan is also good, 
since these together are what you need to set your timing.

Let me know if your threads are shot; I can measure a bolt here 
and send you the thread size. It will be a bit difficult, but you 
should be able to chase the threads in place. The threads are not 
likely to be very bad, so you will need to be careful to follow the 
original threads and remove the minimum material necessary to let 
the bolt thread back in.

I would probably start with a new bolt to make sure that was not 
the problem.

BTW, there is no gland (pilot bearing) in this bolt, so it is not a 
gland "nut."
