I would have to lose 3 belts before my water pump (and fan) stop, 2 belts before I lose the alternator, and 1 belt for the P/S (which I've driven without before).
While carrying a replacement belt would be an obvious and good idea, in 20+ years of owning a variety of cars and trucks with serpentine belts, I have YET to have a serpentine belt fly off or break ( even with repeated 6500+ rpm blasts ). I have seen them shred and go from 6 ribs down to 2 or 3, but they have never let me down whereas I have nothing but contempt and disdain for V-belts that are notorious for failure. I personally HAVE had all 3 V-belts come off in one incident. I would be EXTREMELY interested in a serpentine setup for my AMC's
