Default Alternator bolt stuck

Hey everyone, I'm trying to get my original alternator off, the top bolt is frozen in the head, I've tried pb blaster, but since the bolt is covered by the spacer I don't think it's getting to where it should be, any tricks to getting the bolt out without breaking it? Thanks!

After letting the WD-40 type stuff soak overnight, I like a pipe type extension on the ratchet. You might even try heat on the bolt and apply the 3 foot extension of a floor jack handle on your ratchet.

Really, that much force, what are the chances of the bolt snapping in the head?

If you snap the head off you can then remove the alt and get a pipe wrench or vice grip on the broken bolt with penetrating oil on the threads at the block. I have often found the bolts are corroded solid to the aluminum spacers or alt itself and are not seized into the iron block.

When I loosen the bottom bolt the alternator swivels, back and forth, so it seems the bolt is not seized to the spacer or alternator itself, but seized in the head, so I'm afraid of it snapping flush to the head.

After thinking about it, if the alt. Swivels then it could be seized in the spacer, I hope it is and not the head.

Just watch the head of the bolt. If it moves when you swivel the alternator then it's the spacer. If not then it's the bolt.

This. I've managed to remove the long bolt from the block only to have it fight me for another 20 minutes or so to come out of the alternator.

Heat the block with a torch then ice down the alternator/ spacer.

Will a propane torch be hot enough?

I got it off, I had to cut through the alternator and bolt. Now, i want to replace my 3 belts, it looks complicated, the work shop manual is no help, is there an easy way to find out how to replace the engine belts? Thanks!
