2007 Buick LaCrosse Question: low whining noise at low speed, much like a noise of low power steering fluid



1joseph, 3.8L V6, Reisterstown, MD, December 16, 2010, 18:06

This noise started about three weeks ago. Since then I have replaced the serpentine belt. The noise got louder and increases with acceleration up to forty miles per hour.As far as I can tell the belt tensioner seems to be OK. The noise is constant.
