It's very important not to neglect your drive belts as a failure will leave you stranded. A belt is easy to inspect during normal maintenance such as an oil change or refilling your washer tank. If there are cracks running across the ribs, sections missing, the edges are frayed, or the threads are visible on the belt surface, the belt should be replaced immediately. Also pay attention to a belt that is running off the edge of a pulley as that is a sure sign of an impending failure.
If you can, inspect and test the various pulleys and belt tensioners before ordering your belt. Or plan to order new pulleys and tensioners for a complete overhaul. A failing tensioner can let the belt slip off the pulleys or allow too much slack, causing cooling or charging issues. The pulleys are made of plastic and shatter with age, causing potentially expansive/expensive damage to your engine, radiator, etc. They usually last longer than the belt but now is the best time to replace them. Since they are bolted on, not pressed, they are easy to replace.
