So I have a new update.  I was able to locate the key for the motor and I used a screwdriver in it to help get the motor not to spin when I loosened the screw on the outside.  Well, you trade one problem for another apparently because as soon as I started to turn the screw, it broke off.  I didn't even apply that much torque to it.  Attached pictures.  Does this mean that I need to replace the entire radiator fan motor?  I don't see a way of getting that end off of it to even attempt to get the screw out.

At this point I would say you will probably have to remove at least the overhung adaptor. You have a little bit of the bolt sticking out, not sure if you can grab it with a pair of pliers and get it out. Wondering if this is reverse thread? I have a pair of knipex pliers that are my go to for removing stuff like this, they really grip much better than vice grips. The ones I have are called the alligator. Not sure how much an overhung adaptor costs but might be worth taking it to a machine shop and having them extract the bolt for you, depends on if you want to try to mess with it. You could remove it, I would probably try drilling it out if I could not get it out with pliers. Your going to need really good drills to drill it out though, you need to be centered so you can drill most of the bolt out except the threads then you can just run a tap down in the threads and clean them out.
