Hey guys, heads up if your water pump goes on your 2.5 duke. There's about 8 different varieties of them (single pulley, 2 pulley, 3 pulley, single and serpentine, serpentine, serpentine with 2, and no pulley). Part stores stock the water pump with NO pulley, but i'm guessing a lot of us have the one with the pulley attached. Of course no one had it, and it's a 2 day ship from the warehouse. The only place that could order it was Autozone. Advanced Auto, Pep Boys, nor Napa could not get it.
