2000 Contour SE Sport V-6/MTX, 47,000 Miles

I get a loud high-pitched noise from the engine compartment on startup when the engine is cold (sitting for at least 4-5 hours) and wet.

The following conditions apply:
1) The noise is heard regardless of whether car is moving/in-gear or stopped/in-neutral
2) The pitch of the noise is RPM-dependent (it gets higher pitched when the revs increase)
3) The noise lasts only for a minute or two once the car is driven.
4) The noise sounds more like a whistle than a screeching, leading me to believe that it is not an accessory bearing. Howerver, I can't confirm that it is a whistle.

Thanks for any suggestions!




If its coming from your serpentine blet area its gotta be the power steering pump. I have the same problem you have and if the engine is somewhat cold and start it up and makes the noise and it goes away after 30 secs. Do you have a leak underneath the power steering pump?? If you do replace it if not its gotta be something else.
