Weird noise from around alternator or belt
I have a '98 Ford Taurus LX with a V6 Vulcan engine. I am getting a weird noise--kind of like the whine from the gears when someone drives in reverse in an older car--when I have the engine running. The noise goes up in pitch as the engine turns faster, but does not disappear when I am idling. After driving for a while, the noise sometimes disappears. I have opened the hood while the engine is turning and can hear the noise seems to be coming from somewhere around the alternator, belt, or somewhere in that region.
