I experienced the same problem over & over again over the course of 2 years (horribly squeaky belt due to a gross misalignment which caused the belt to either break or slip off at least once every 4-6 months); replaced tensioner pulley assembly, water pump, a/c compressor, drive-shaft pulley (harmonic balancer), alternator...finally took it in to a competent, experienced & honest mechanic who told me that this was a very common problem with this make & model...so much so that a new "belt kit" had been designed & was available; most of the pulleys on this model or grooved except the tensioner pulley, idler pulley & water pump pulley (which are smooth); therefore, the serpentine belt is grooved on one side & smooth on the other; this new belt kit has a tensioner pulley and idler pulley that are both grooved & a serpentine belt that is grooved on both sides; both said pulleys and the belt were replaced & the van has been squeak free with no belt misalignment or belt failure (breaking or coming off) for a couple months now... needless to say, I'm plumb thrilled about how things finally turned out!!
