Crankshaft end bolt removal

["Hugh Fader" <hfader@usa.net>]

Well. I have another stuck bolt on my TR6: the crankshaft end bolt. I have
two of the radiator bolts installed and am holding it from turning with a
screwdriver between these. I have sprayed the bolt with Kroil and gave it a
few whacks. Trying to turn it with a big adjustable wrench. This isn't a
left-hand thread by chance is it? Next step I guess would be heat, but where
to apply it? It looks like the threaded hole is behind the pulley.

Any suggestions?

Thanks,
