86 coupe - Crank pulley bolt & loc-tite

[Fred Munro]

Mark;

If you feel you must use something, use Loctite blue (242) under the head of
the bolt, not on the threads. This locks the bolt head to the pulley. I have
seen locking compound applied from the factory in this fashion on some
original bolts I've removed. I use Loctite blue under the bolt head when I
install the crank bolt. Don't use the red or you'll be cursing at the next
belt change.

Does anyone know what type of loc-tite can be used for this bolt.  I
have a Red, "high strength" product made by Permatex.  It claims to be
used for torque up to 240 lbs.  But also says parts must be heated to
500 degrees before they'll separate.  This could be the last time I ever
change the timing belt on the 86 coupe if those parts set up like that.
Seems like I read in someone's instructions to use Loc-Tite 242, but I
don't know how this compares to the stuff I have.  Any thoughts?
