Now, I don't know if this is what happens prior to the AC compressor going out or not but I've had this issue for about a week. My S-belt started squealing so I figured my belt was faulty. I replaced the belt and the sound slightly went away, but not completely. I then noticed that when I turn my AC on, the sound completely goes away. I want to assume it's the whole pulley or AC clutch but I don't know what to look for. My AC works fine and I haven't had a problem with it because of this issue...any thoughts? I noticed my belt is slightly off because my arrow doesn't lie within the rectangle so perhaps, and hoping, it's just that? I also don't know how to adjust that, though...:squint:

Arrow doesn't lie within the rectangle? Maybe I'm having a slow moment, but what do you mean by that?
I think he is talking about the indicator that tells whether the belt's auto-tensioner is within spec or not.

If it's out of range, then the tensioner is bad.

Do you believe it's only that or something related to my compressor as well? I'm just kind of confused because the noise goes away once I turn my AC on. And yes, the auto-tensioner...I didn't know what to refer it as...haha

Not only should the auto-tension be in the range of the 2 rectangles, it should be on the tight side.
The tension is adjusted by changing belt lengths.

I think your original serpentine belt was worn & your new belt is too long. I recommend to try a shorter belt.
It's not uncommon to purchase several lengths of serpentine belts, trying several on for size & then returning the ones that you don't use.
