When I accelerate there is a high pitched squeal...

Every time I accelerate from a stop or I'm in the 2,000-3,000 band it's present. What could this be caused from?

I thought it could be a belt but the serpentine belt looks fine with no wear on it. Could it be the timing belt? How can I tell it this is the problem?

Any other suggestions?

(Sorry if this is in the wrong section)

Just because you don't see anything VISUALLY wrong with the belt does not rule the belt out.

The serpentine belt is cheap.. I'd replace it if you haven't in a while.

its the belt itself its dry and probably cracked. i would replace it. its the piece of mind that it wont break going down the road.

So it's the serpentine belt?

I'm going from Maine to Mass in a few weeks to go to six flags and I don't want to have to call AAA.

I want to be ready

It could be an idler pulley also. Have you tried it with the hood up, and opening the TB by hand to rev the engine? It may give you a better idea where the sound is coming from. Just be sure it is in park if ATX, and/or the brake set/wheels chocked if parking brake doesn't work.

I always thought that sound was the squirrels in our engines doing their jobs.
