I am having a chirping.. intermited sound under my hood... when it starts it dont stop.. faster I go faster the chirp. I checked the serpentine belt and all fluids... all are fine. my dad said something about a pully that keeps tension on the belt he had a chirping in his ford van... and it was that.. only I do not know which pully that is... I know the alternator and the power steering.. I know its not the big one on the bottom mian drive shaft i think.... can anyone help me.. or have a diagram of the pulley system

Thank you

Spray the one you think it may be with silicone spray to see if the chirping stops. If thats not the one, move to the next. Spray them all until you find the right one if you have to.

You can also use a long screw driver to put on the base of each pulley, then put the handle next to your temple to see which one is squeaking.
