Squeal under hood at low RPMs has turned into chirping
I think I may need to replace my serpentine belt but I'd like to get your guys' opinions.
My belt has been squeaking for some time now but the sound would usually go away after a few minutes of driving.
Recently the noise became louder and is now more of a "squeal" than a squeak. As of a few days ago the noise is constant at low RPMs (e.g. even after a prolonged period of driving the noise comes back when I'm at a low RPM).
I opened the hood and when I revved the engine to ~2k RPM the noise completely disappeared. Once I let go of the gas it starts squealing again.
Does anyone think it can be something other than the belt?

Do I need to remove the belt in order to check the pulley?
As well, I found this thread https://g35driver.com/forums/engine-...ine-belts.html and there's a diagram that shows two idler pulleys on the alternator belt. Which one am I interested in?

What's the condition of your belt.
I've found these belts stretch over time. Every time I change out my belts, I need to crawl under and retighten because they stretch and I get a slight squeal when I start the car or the engine was cold or I drive through water. You'd think a cat was getting killed under my hood.
If your belts are ok (no cracks, splits or drying out) then just loosen the two pullies and tighten up the adjusters a few turns and then retighten the idlers. Give that a shot.

Belts both seem fine and pretty taught. I will however try to tighten the pulleys a bit and see if that solves it.
While searching I found a nice and simple way to help determine what's making the squeaking noise - belt or pulley. Simply spray some water onto the ribbed side of the belt and if it stops screeching then it's the belt and not the pulley. Here's the video:
