Am I going nuts? Engine fan nuts not loosening

[Pergatory]

Hey guys, I wanted to consult the forum before I resort to any drastic measures, since I've never run into anything like this before.

I'm trying to get the fan off my SR20DET so I can change the belts. There's 4 nuts holding the fan coupling to the pulley. First one came off just as you'd expect. The remaining 3 simply don't come off. I can loosen/tighten them eternally and there is some resistance but they are not moving up/down the thread of the bolt. The bolt is not spinning with the nut or anything, yet the nuts are still not moving. What the hell is going on? Anybody familiar with this and wanna give me a clue? I'm sure it's something stupid and simple that I've just never run into before...

Thanks in advance.

Sounds like they are stripped. Can you see any damage?

stripped studs, cut 'em off.

PB Blaster or Liquid Wrench

Let it sit, go at it again but with a bigger lever arm.

Yeah I have run across a few cases where the water pump nuts wouldn't come off due to stripped studs. Sometimes if they are loose you can put a screw driver behind the nut and put outward pressure on it and they will catch a thread and come off. If not, cut them off and get new studs.
