The belt routing diagram should be under the hood on a sticker on the hood or front cap over the radiator. If the sticker is not there any more then you can pick up a haynes or chilton manual. These cost about $15 at your local parts house. There aren't any free sites that i know of that would give you a diagram unless you subscribe to there service for a year. Then they hit you with huge fee's. Then its just not worth it. Hope this will get you going. Good luck.
