Are you may be talking about belt squeal?  And that too needs to be fixed before you chew it up and loose the water pump on the highway.

Subject: Re: High pitched noise

I've heard that high pitched noise upon startup, but it goes away soon after I start driving.  And I don't hear it every time I use my van.  Is it really that bad if it I don't always hear it, and when I do, the noise stops within 5 or 10 minutes?
