The Renesis water pump is driven by = the grooved side of the belt and rotates in the same direction as the engine = and alternator.  I don’t know if that is reverse of the earlier = 13bs are not as I don’t have one, but I doubt = it.

The only thing that runs on the = back side of a belt on the Renesis is the idler pulley for the AC = compressor.  This is a separate belt and does not have anything to do with the belt for the = water pump and alternator.  The water pump/alternator belt has no idler = pulley, tension on it is adjusted by the alternator.
