I have a 1996 Sable LS. I just recently purchased the car and the serpentine belt let go on me. I put a new one on and today drove less than 5 miles. When I arrived at home I got out of the car and noticed a burning smell. I looked to the passenger side of my car and there was smoke billowing from the hood. Of course I opened the hood and noticed it was coming from the bottom of the pulley set up. What could it be?
