I have a 2002 pontiac grand am. A while back the serpentine belt started squeaking, but it wasn't very loud so I left it alone. Lately the belt is really loud and gets louder as I accelerate. I wanted to know if it can be fixed and for how much. I am in high school and work at a fast food resturant, so I don't have a lot of money, but I just want it fixed and to stop squeaking.
