So I decide to replace the water pump on my 90 16v... One of the 4 bolts that secures the water pump to the block has snapped, leaving only about a 1/4" exposed. I've tried liquid wrench, smacking the bolt with a hammer, and propane torch all while trying to just get the bolt to break loose with the vice grips. I gave up and attempted to drill it out and use a heli-coil, but my small "starter" cobalt bit broke off in the bolt, so now it is impossible to drill.
Any suggestions before I replace the block? There has to be some fitting for my dremel or air grinder that could get through the bit in the bolt. I am going to do some searches on the web to see what I can find. Chad
