This is a very involved procedure, that is too complex to post here. Go to any auto parts store and purchase a repair manual for your ride. There you will find detailed instructions. Cost around $12
The Haynes manual will tell you all about it. or a Chilton's repair book. at the local library this is free step by step!
But, I had it done by my mechanic, it's kinda a pain to do it yourself.
(took them 6 hours)
Change the water pump and the idler while you're at it, that car is a pain to fix...
