This can be potentially dangerous: while driving, the ac tensioner finally locked up and caused our ac belt to snap, taking the serpentine belt with it. Suddenly lost power steering on a busy road, with no coolant pumping or battery charging either. Had been chattering/rattling for a while beforehand, but had no idea what was causing it until now.
