Not all RTV is compatible with ethylene glycol. It should say on the
package.

Re: Best method for extracting bolts with broken off heads...
So far, bolts 2, Clint 0...
I've tried the penetrating oil, beating my fustrations on it (gently, so I
don't damage anything worse), trying to grind off some flat spots for the
vice grips to grab. No joy so far.
Next up:
Has anyone tried these Irwin devices before?
http://www.irwin.com/irwin/consumer/...rwinProd100519
I've tried a couple of places, but no luck finding some of the other ones
mentioned. I'll do some more looking tomorrow, though.
I'm concerned about trying to drill into the end of the broken off bolts,
mainly because I'm not to confident in my straight-line drilling abilities
(especially in metal), and the vertical support bar on the front grill is
right in line with the two bolts I have to drill, so I'm not sure I'm even
going to be able to get a drill in there.
I haven't tried the torch heat/cool cycle yet, mainly because I'm concerned
about an engine fire. I should have a fire extinguisher in the garage in
any case, but I don't currently. And with penetrating and engine oil all
over the place...
Thanks for all the helpful advice so far.
