buy a "Haynes" manual or a "Bentley" manual for that car.
Well for the fan belt its really simple: You need: a 13mm Socket, a 6mm Hex bit, and a ratchet, a large crescent wrench would also be helpful.
1. Loosen the 6mm bolt that holds the alternator in. 2. Loosen off the 13mm bolt that is on the bracket. 3. Take the old belt off. 4. Put on the new belt. 5. Slightly tighten the 13mm bolt, and use the crescent wrench to tighten the belt (using the half gear/half nut tightening assembly) 6. Tighten the 13mm. 7. Tighten the 6mm.
Done!
