Starting yesterday, either my serpentine or alternator belt has had prolonged squealing accompanied by a burning popcorn smell. The alternator belt was replaced 2 months ago. After the first occurrence, I replaced the serpentine belt thinking that the smell was from the belt burning somehow. After replacement, the smell and squealing has happened again. I cannot detect any burned insulation on any wires around the source of the smell (rear middle of engine bay above the belts.) The burning smell only occurs when the belt is squealing. The few times the smell and squealing occurs, I have pulled over and looked for smoke but have not seen any. I'm guessing that rubber is burning somewhere, but everything I have found online says it is burned electrical insulation or an electrical short, but I don't understand why the smell is always accompanied by the belt squealing. What should I look into further to find the source of and fix the smell/squealing? The belts also are not loose.
have the same problem?
