The serpentine belt is the large belt on the front of the engine. It drives the accessories (alternator, fan, etc.). It's not hard to replace. There should be a "serpentine belt routing diagram" sticker under the hood to show you how to put it on. To remove the old belt you'll need to release the tention on the belt. Using a breaker bar move the tentioner opposite the direction it's pushing on the belt. Slide the old belt off and release the tentioner. Put your new belt on the pulleys, following the diagram. Now using the breaker bar again move the tentioner like you did to remove the old belt. Slide the new belt into position and slowly release the tentioner. It'll probably take less than a half hour to do. HTH. -Jim

Jim is right, as always, but the guys at those oil-change joints will always say your serpentine belt needs to be replaced. Give it a good inspection yourself. If there is fraying on the edges, cracks in belt, obvious signs of age them sure, you need a new one. But if it looks good, and has less than, say, 60,000 miles then they are just pushing something you don't need.

Dont trust the sticker under the hood, Draw yourself a picture before you start of where it goes exactly, and if you have any doubts about the condition of the belt then do it. Preventing problems is always a good plan
