It is pretty easy actually. Check out this link.
Take off your belt and start the car, listen and see if it makes noise. If it is quiet good chance it is a belt or pulley somewhere. If it squeals with no belt look at repalcing the CPS. I would not buy a cheap CPS. They do not last like the factory ones.
