Started a quick thermostat and expansion tank replacement this weekend.....
...f'ng remnants of this bolt are not budging....I'm weighing options on how to remove it....no amount of pb-blaster and locking pliers will get it to budge.
was that t-stat leaking? just based on the amount of corrosion above that bolt where the gasket was, makes me suspect that bolt has had some coolant chemical warfare enacted on it.
how tight are you getting the vise-grips? i highly recommend the flat-jawed ones. get them as tight as you can, and then tighten it a little more. and more PB Blaster - spray, let sit for 5min, then go at it again. back it out s l o w l y . . .
oh ya - and prayer works better than anything else.

Yes...it appears as though it has...but it couldn't have been more than a dribble because I never had a puddle nor was I needing to add any coolant. So yes, that coolant mixing with the cheap steel and the aluminum wreaked some havoc. Unfortunately, I have clamped the vice grips down and it just refuses to come out....I've sprayed pb nightly on it. Im feeling Im going to have to drill it. I was toying with the idea of welding a nut to it but not sure what that would gain me other than the bolt breaking further in to the head.

You need to heat that up to get it out and you're going to have to get it pretty hot. Make sure your heating the area around the broken bolt, not the bolt itself...
