Ive read that most Taurus cars have a faulty pulleythat the serpentine belt runs through which makes irritating noises such as squeaking, humming, tilted steering. It must be replaced to fix the problem. Belt conditioner is a temporary fix however u would have to use it daily. Highly reccomended to just get it replaced. hope this helps.
