Constant squeak/chirp from belt up front... alternator?
What's up guys... my warranty just ran out on the Z, and of course immediately I start hearing things. It's not insanely loud, but it's there, and it wasn't before. It's not the loud screeeeech that I often hear, but I feel if I let it go it will get like that. It's just a constant squeak/chirp/high pitched winding noise, however you want to look at it. I popped the hood and it's the belt you can see right up front on the right side of the car (left if looking under the hood). Is there an easy fix for this, or should I just bring it in, or extend the warranty???
30k mile warranty (left over, bought it used), now at 31k.

don't worry not a big deal. You can stop the screatching from putting butter, yes i said butter on the belt. This will cause it to stop squeaking. Another thing you can do is get wd-40 and put a liberal amount of it on your belt will fix that problem. I know because i had this problem at one time, your welcome. Yes, it really works just do it you will be pleased with the outcome. my belt started squeaking at the same times yours did lol. Im at 50 thousand now and no squeaks. Before i did this it squeaked all the time it wasn't super loud but its just loud engough to get you annoyed i know how you feel.

my squealing sound never came back, i got my belt checked and it was tight. If the temperature fluctuates alot it will cause the belt to squeak. I live in texas and the temperatures have been crazy 40 one day 80 the next, rain the next. This caused my belt to start squealing. So, if you check your belt and it is tight you might want to try my method.

BTW, just because you think it's tight, it may actually not be. The Service Manual says to apply 98N (10kg). Unless you have a tool to measure and apply force accurately, you'll just be going off by feel (inaccurate).

Thanks for the tips everyone... I may just take it in to get tightened or replaced. As for the WD40/butter method... where on the belt would you actually put it? On the inside of it? Wouldn't that decrease the friction making it slip even more? I may give it a shot of it doesn't hurt anything.

i just put it on the top and bottom of the belt. i would use wd40 because its alot easier you will hear the sound go away instantly when you put it on. turn the car on and while the belt is moving spray it on the belt. I did it at 30,000 miles im at 50,000 miles still no squeaking.
belts making noise can be from different factors like the people stated a above. You might need a new belt, might needs to be tightened, or the weather can play a role on your belt squeaking because your belt contracts and expands a bit depending on the temp excspecially when the temps. change drastically where you live.
I would look at the belt see if it needs to be replaced , if not then try tightning it, if that doesn't work pull out the wd40 and that will stop it.

My belt makes the same awfull squishy/whinning noise for the first few minutes on a cold startup.
Both belts are tight and look to be in good shape. Its too cold to lift the car and change them so I'm going to try a little WD-40 in the mean time (belt dressing only made it louder).
My spidey sense tells me WD-40 is a bad idea but I didn't see any negative comments.

Yeah that belt dressing crap should be illegal. It made my belts worse and made a mess under the hood. I thought it would be a good temporary fix until it warmed up around here (so I could change the belts more comfortably), but it actually made my belts LOUDER!
