Frozen water pump bolt

I hate easy outs too.
Hitting the cover with the torch is pretty tricky, but I got that to work once. I had cut the head off as suggested. Then heat. But it was no easy job, as I had to learn how to heat that great big heat-sink of a cover, without heating the bolt at the same time. If it happens to me again, I will try something else, cuz the torch method was a PITA.

One idea I had,for next time, was to Zip-cut right through the aluminum cover and the bolt, about 1 inch from the block. Then remove the cover to the bench to punch out that bolt.And finally Tig the slot up. Getting the cut-off stud out of the block should be pie. Just an idea at this time.
