so i got a sqeak problem on my 06 v6, automatic mustang. When i ccrank it i can hear it, while idling it stops, when i accelerate it sqeaks. I cant tell if its a puley or a belt. I pulled the belt off and it looks brand new, no cracks no chips in it. I sprayed behind every pulley with some lubricant, but it did not stop the squeak. So i dont know what to do, someone please send some help my way.

Sounds like your belt is slipping somewhere to me. try adjusting the tensioner

cycle ur ac and see if its when its on or off or both

how would i adjust my tensioner? Also a few nights ago i took it for a drive and it did not sqeak at all, so sometimes it doesnt do it.
