I have posted an earlier question inquiring about a belt noise. After many needless parts replaced I now believe the culpret is the High tech fan clutch. The truck only makes the noise when hot and Today the squeal continued after the truck was shut down for a second or two. Has anyone had this problem. The Truck is a 05 Dodge with 21k miles. It all started after towing a heavy load this past spring. It is an annoying sound like bearing failure at idle when the truck is hot.
