Weird noise coming from under the hood?

[Jonnathan_]

Deep whistling or swooshing sound coming from under the hood at idle.. not sure how ti describe the noise but its almost like a really low pitch whistle or low pitch screatch
ive tried researching what it could possibly be but i cant find anything and i work all day so i cant take it to a shop
Not sure if it a pulley or what. Im going to try and post a video
Its on my 01 GT 4.6 2v btw

It's hard to tell from your vid, but Remove the Belt and start the Engine for a few seconds, if no noise then it is one of the pulleys (idler most likely) or the belt.

Exhaust sounds good at least

Brother, yank that belt first and see what happens.

Depending on how old it is a new belt and idler pulley may not be a bad idea to replace anyway. Pretty cheap and you are already in there!
