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! 2000 Contour SE Sport MTX Mods (so far): BAT Water Pump, Dual-Mass Damper

Then I would remove the belt and start engine to see if noise is eliminated. Inspect belt grooves carefully and also look at idler pulley and other drive pulleys for any obvious wear. Is your belt original? 1995 Mercury Mystique LS OBD1 2.5 L Duratec ATX- No modifications 70,000 Miles w/ O.E.

OK, i dont think it will work but i bite and get it.. so far about 2 months no problem with the belt...hope the redesign is correct on this belt... I checke auto zone, pep boys, advance auto parts, NAPA and some other parts sites and found that on some of the sites that the belts for the contour have two different measurements on it.. about 1/8 in longer on some belts... wonder if this would be a problem?????? never had to get into that as i got info from ford that the new belt i bought was the replacement for the two older belts that were replaced on my car.....

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. Irfan Rahim irfman2000@yahoo.com 2006 Blue Nissan Sentra SE-R Spec V Former owner of a silver 2000 Contour SE Sport ATX
