Squeeling sound under the hood Options

[H1gherReflex]

This has been happening for awhile now. Initially I had a bad serpentine belt and replaced it. The sound stopped for awhile but eventually came back. Now I have no idea what is causing the sound. I added power steering fluid and that worked to a degree but now that doesn't have any affect at all. The sound seems to stop once I either hit a certain amount of RPM's or once the car has been in motion for awhile. I was wondering if anyone could give me some answers. Here is a vid for further examination.

Try getting some belt dressing (it comes in a spray can, you can buy it at any parts store) and spray the inside of your belts with it, and see if the squealing stops. If your belts are on properly, and they're in good shape, you could just need to apply that belt dressing which will stop the squealing noise.

HOWEVER,

I had a smilar problem and used belt dressing. When I had applied it the noise got worse (much louder). Turned out it was my alternator pully.
