[ video] Mustang making a whistle sound from belt / alternator area
Recently she has been making a whiney noise from the engine. The video is below. I've had a suspicion that it may be the belt tensioner. The alternator was replaced just about 2 years ago so I don't think it's that.
If anyone has any ideas, please shed some light.
