Heat it as much as you can for a few minutes. (It does not have to come cherry red). Apply water immediately after until the bolt becomes cool. Repeat this process if necessary and will be easy to remove.

you jest need to get it hot if it is a small propane torch about 1 to 2 minutes should do the trick if not heat it up for a minute or two more but you never want to get the bolt to hot you will compromise the strength of the bolt what you really want to do is heat the area that the bolt is in heat makes metal expand so when the surrounding area is heated it expands and the bolt can then be removed

Heating and the cooling is what expands and then contracts the bolt thereby loosening the rust connection. Also when fairly cool apply a bit of "break free" or similar material to help loosen as well as lubricate the rusted threads.

If you heat the bolt itself heat it until it turns cherry red, but you must let it cool back down first before trying to turn it. If you don't wait long enough you will just gall the threads turning it out since heating it expands the metal.
