How do you change a serpentine belt on a 1998 Chevy S10?

My serpentine belt broke yesterday, and I heard it%26#039;s not that hard to change. I changed one a long time ago on a older smaller car, does anyone know is it easy? Or should I have a professional do it?|||Not too hard, you just go by the routing diagram if there%26#039;s not one under the hood you can go to AutoZone or somewhere and they can print one out.|||easy to do, use a breaker bar to loosen the belt tentioner, and slide the new belt in place,,,,,|||do it the right way release tension on idler pulley by lifting up or pushing down follow diagram on radiator shroud
