Broke my water pump bolt. Now what? (Update - broken bolt is out)

Probably not enough for that extractor. You do gave a little material to weld a nut on though. The ones that break off below the surface are tough to weld a nut on. You have to build up weld to the surface. A welding or machine shop is your friend.
Yeah, I agree that my local machine shop could have it out in a jiffy. As always, transport is the hangup. I have no way of moving the engine there. The motor is on a stand in my garage and weighs about 400 lbs. dressed. I don't have an engine lift or tow vehicle, nor do I own any welding equipment or have any experience welding. It would be a very simple task for my machine shop guy, as I've brought him smaller items before for bolt extraction. So I'll just have to get creative and use the drilling/Easy Out/Liquid Wrench/hammer tapping methods and all the other great recommendations that guys have sent me. One way or other, it's coming out. Right now, it's soaking in PB Blaster. I know that if I could get it cherry red, it would come right out but I don't have the stuff to do this, other than a small hand held propane torch used in plumbing. I'll keep working on it, though. I already have the new water pump from NAPA and I'll install it ASAP once the bolt is out.
