Default Squealing noise from drivers side of engine bay

Hello, my car has developed a squealing noise from the driver's side of the engine bay, kind of sounds like a belt noise so i'm assuming it's the serpentine belt. So far everything is working normally on the car so where should I start as far as diagnosing the problem? I don't want the belt to snap on me lol. Thanks for the help.

You can spray the belt (both sides) with brake clean while the car is running and if the squeal momentarily goes away, you have a noisy belt. If it keeps squealing try taking the belt off and spinning all your pulleys by hand and see if they make any noise or feel "rough".

also take the belt off, by putting a 15mm i think wrench on the tensioner pulley and pry down to take it off then give yer tensioner wheels a spin to check the bearings,, they go sometimes too. I would assume its the belt tho.

Thanks for the advice guys. I sprayed the hell out of the belt and it kept making noise so i'm assuming it's a pulley or something like that. How would I go about pulling the belt?

As BCKNBLK said take a 15mm wrench or socket and push the tensioner down to relieve pressure on the belt.
