86 coupe - Crank pulley bolt & loc-tite

[Ameer Antar]

You don't need any Loctite as long as you tighten the bolt to the right torque. Some people have had problems with that bolt b/c they did not tighten it properly. My Bentley shop manual says to use an anti-corrosion chemical (i.e. WD-40) on the threads, so this would actually prevent you from using any Loctite. The bolt is supposed to be tightened to about 330-350 ft-lbs according to it's size and class, unless you use the Audi extender tool, and then I think it's about 250 ft/lbs. That's pretty tight, even for an impact wrench, so make sure you know it's at the right torque. I wouldn't really count on Loctite to compensate for a loose bolt anyway; it's really to prevent a properly torqued bolt from vibrating loose. good luck.

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?
