03 7.3L fan replacement

I attempted to post in the help thread but couldn't.
My wife fired up our 03 7.3L Excursion today and there was a cat in the engine.
The serpentine belt was destroyed and 3 fins on the fan were broke.
I bought both parts today but have not been able to get the old fan out.
No matter which way I turn the fan nut the clutch spins. I can not get the old fan out. So I figured it was doing this because I didn't have a belt on.
I put the new belt on but still can not get the nut off to remove the fan/shround assembly.
What in the world am I doing wrong?

Get a bigger hammer. j/k. There is a special tool to remove those fans. It holds the fan hub so you can remove the nut. If you're lucky your local auto parts store has one for rent, or...

Or if you cant get the wrench, use a chisel and put it on the edge of the nut (make sure you check if it is right hand thread or not and place the chisel appropriately) and just hit the chisel with a hammer a few times.

Cat ran off into the pine trees. My wife said it wasn't good - big chuck missing out of the hind end.
Blood and hair everywhere when I got home.
Can't find the cat anywhere.
