snapped bolt
the lower right bolt on my water pump snapped off flush with the block i tried to drill it out and either use an E Z out or drill it out bigger and tap the hole bigger, but does anyone have another suggestion of something i should try.

Yikes, I hate it when that happens.
I was too scared to even try to remove mine...and I had broken 5 exhaust manifold bolts when strippin down the Caddy engine. Did you mess it up with the drill? |

If you have a wire welder, you can put a nut over it, and weld the nut to the bolt from inside the nut, does that make sense? ,anyways weld it up, and with the new nut, combined with the heat it should come loose, always works for me.
lots of luck!

Hmmm, a few ideas come to mind, drill and tap then screw in a threaded insert to match the original size bolt.
OR/ Drill a hole in the bolt as far as you can, heat the bolt w/ a propane torch, then squirt water in the hole. The heat should expand the bolt and then fast cooling might make it contract away from the threads in the block. Then get an easy-out in there.

bit
Use a left twist drill bit and it will either give you a hole for the extractor or spin the shank out. If things really get out of control you can try to burn it out as the metals are dissimiliar and then chase the threads with a tap. good luck

Dang, I wish I had thought of that welding the nut thing before. That could have come in handy! Oh well. Bunch of good ideas.
