Argh.. this has been a consistent problem.. more like a major annoyance for me for the past few months. At idle, and as I increase the RPM, a high pitched squeal emits from the drivebelt area under the hood. I've checked it out, and it is almost certainly coming from the crank pulley. What can I do to fix this? Like I said, it doesn't seem to be coming from any of the accessories, but from the crank pulley itself. Thanks.

 

make sure the belts are not too tight or too loose and maybe oil the pulleys.

 

One of your drive belts is too loose. Check the deflection of each belt and tighten up any loose belts. Squealing should go away. HTH.
