If it is driven by accessory belt, there seems to be this weird possibility that an engine can work itself to death. I think this is what I was trying to ask. Just some clarification.

99% of the half-decent engine designs out there puts the alternator and the water pump on the same belt.
So unless you are a truly ignorant driver to the various lights that will come on after the alternator stops charging, the chances of you blowing up the engine from a belt failure + overheat is next to none.
