I have a LS2 with the the Kwik alternator and AC relocation brackets. Since I've had the car put together, I've had an intermittent serpentine belt squeak that is driving me completely crazy. I've replaced idlers, rebuilt the alternator and am really not sure what to try next. The alignment is perfect. If I add pressure to the tensioner the squeak stays. It does not get any worse or better it seems with the AC on or off. Any thoughts?
