If you're retightening this to spec (350 lb torque, isn't it?), I wouldn't
worry about it coming off.  I haven't had any problem with my '86 4kq that
I replaced the belt on a couple years ago nor the 200q20v that I did last
year.  If you feel you must use something, I'd use the LocTite (is it blue
or green?) you can apply after the bolt is in place that's supposed to
prevent vibration loosening but not require much torque to undo.
