Water Pump Bolt Troubles
Someone must have encountered this one before. T Colvin and I are working on his WP/TB today. A water pump bolt sheared off last night, even after the liberal use of PB Blaster. We drilled into it, inserted the extractor, and the extractor sheared off.
What next? How do you get the extractor and the bolt out?
Thanks,
Matt

Try some heat with a torch.
Too bad you broke the head off the bolt. Most stuck bolts can be worked loose by incrementally tightening and loosening. But you need to feel that bolt is getting stuck before you exceed the shearing torque the bolt; that's where the experienced mechanic will usually stop.

Do either of you have welding experience? If a nut or bolt can be tacked onto the extractor, you would then have something to turn, and applying heat to the area may then be enough to get the original bolt broken free.

7 out of ten of my WP bolts snapped. Keith used Vice grips to get the studs out except for one and the same happened as you describe. Ended up having to drill around it and then using a heli-coil.

Try some heat from a propane torch to get the area expanded.

Here are some photos of the bolt. Sorry about the blurriness. It's hard to get a good angle on them.

Second vote for left hand drill bits. Dremel with diamond bit might eat into extractor remains but it takes time and many bits to get even small piece out.

Try heating as scotsman suggested and tap in the opposite direction with small punch. Not having a mig it will be time consuming. I have been able to shatter broken taps and extractors, they are brittle.
