    I recommend using lock tite.

    Mine loosened up after driving for a while at first without it.

    Glad I caught it.

    We had a member here grenade his radiator for the very same reason a while ago.

    The pulley bolt's that connect the clutch to the pulley do have locked flat washers on them.
