The Serpentine drive belt should be inspected every 10,000 miles and you should look out for cracking, however small cracks are normal but large deep cracks are a sign that the belt should be replaced. To replace a serpentine belt you have to loosen the engine mounts and raise the engine up a slight bit, then remove the old belt and replace it with a new one, remembering to tighten the engine belts back up. 
The Serpentine belt is a single, continuous belt used to drive a multiple of peripheral devices in an automotive engine such as the alternator, power steering pump, water pump, air-conditioning and air pump as well as other devices. The belt may also be guided by an idler pulley or a belt tensioner which can be spring loaded, hydraulic or manual.
The serpentine belt is more efficient than the older multiple belt system and consumes less space in the engine compartment by using a single wider belt instead of multiple thinner belts. Higher tension reduces slip which increases the belt life and mechanical efficiency. Reduced belt slip can allow for the use of lower ratio pulleys which reduces the load on the engine, helping to increase the fuel economy and available power. A serpentine belt is much easier to maintain and replace, since there is no need to remove multiple belts in order to remove one of them.
On some engine designs the smooth side of the belt can even be used to drive some accessories, these generally need less torque.
The drawback of a serpentine belt is that if the belt breaks the vehicle loses all of it peripheral devices.
