I'm not sure how long my car has been making a squeaking noise from the pulley/drive belt assembly as I can't hear it from inside the car, but today I left the car running and hopped out and noticed the noise. After popping the hood I noticed that it came from the pulley/drive belt assembly. I'm not sure why it is doing this, but can it be fixed? Also is it damaging my car in any way? This isn't the standard noise from having your belts too loose. It is doing it all the time while the car is running from what I can tell. Thank you for any theories as to what is causeing this.
