I have the 2 torx bolts in the front already loosened, no prob. But the regular bolt in the back of the alt is really giving me a problem. I actually snapped off one tool already! It is a 10 mm bolt. I put a 10 mm socket on it, and all it wants to do is round
its corners off ! Sprayed some liquid wrench on it, tapped it a lot with a wrench. What else can I do ? Vice grips, maybe but that would wreck the bolt, right ?

you kno what works great is pentrating oil, you get it dripping covered with the stuff and let it sit overnight. Works wonders

 

If you've already got all but one of the bolts off, try wiggling the alternator. You may find a certain point where the bolt will just come out by hand.

I'm not positive where your frozen bolt is but did you try putting heat on it?

It's the bolt in the back on top. Just a 10 mm regular old bolt. This is a TPI setup, and now I notice the alt isn't attached at all like my other car. There's no room to loosen the alt and get it off the belt. Maybe I need to do something with the belt tensioner ?
No, I haven't tried heat yet. Good idea, but I don't have a torch.
