    I found the green locking compound Scott mentions on the pulley-to-crank
surface and bolt head when I did the T-belt on my '91 200q. The compound was
not on the bolt threads. I replaced it with blue Loctite. Actually, I
suppose Loctite can be considered an "antiseize" compound - IME it does seal
threads and prevent corrosion.
    BTW, this is one bolt you DEFINITELY don't want to come loose - this had
a bearing on my decision to use Loctite.
