The tensioner pulley for the main serpentine belt is making a noise that sounds a bit like the sound you get when you put playing cards in the spokes of your bicycle, but a little higher pitched and not as loud certainly. It has slowly become louder over the last few thousand miles...

Comments, suggestions???

Thanks everyone.

Have you taken it off to look at it . I forgot to tighten mine up and it fell off . But if I remember right , there is a bearing in that pulley . So you should just be able to go get one at the dealer and replace . If that is the problem

 

Ditto. Double check that everything is at the proper tension and all the pullies are tight.
