I have an 02 Durango with the 4.7l V8 and this morning it developed a squeak. With the heater on hi there is some kind of squeak. I don't know where it is coming from, so I don't know if it is the fan belt or the fan motor. It does have a 132,000 miles on it. Any suggetions or ideas would be greatly appreciated.

 

fan belts squeak full time or just until they warm up. If it is under the hood listen to water pump, ac clutch, etc.
