is it usually a belt noise or a water pump?? The vans i always head pretty
loud... wasnt sure if they were a belt or a water pump...
was wonsering if this was something common with the E series vans??
Belt noise can be cause by any of the accessories the belt is driving. Water
pump, power pump, A/C compressor. Back in the early 90's the 4.9 had a drive
belt noise caused by the water pump pulley loosing it's coating. The areas that
lost it's coating caused the belt to squeal. Other than that, I do not believe
there is any one part that fails like you are suggesting. About the only part
that is "common" to belt noise today is the automatic tensenioner, as that over
time it looses tension allowing the belt to slip.
