The first thing to look out for is the tension and general condition of the belt to ensure that the vehicle is always ready to perform. An over stretched belt will easily wear. There are several things to look out for when inspecting the drive belt. These are cracks, the presence of frays, missing ribs or the presence of any logged foreign material. If one observes tiny cracks in grooves, that is normal but deep fissures,splits as well as frayed edges or cracks that run parallel to the ribs should be a cause for alarm. Other warning signs include a belt that exhibits a glossy appearance or one that has some of its rib sections, half an inch or longer, missing.Additionally, one should ensure that they inspect the entire length of the belt surface. If any of the above mentioned elements are observed then it is time to change the drive belt. Sometimes, the vehicle may produce a squealing sound. This typically points out to a loose or worn out drive belt. This is because a loose belt may slip and subsequentlyproduce a squealing sound, causing the alternator to vibrate rapidly, thereby wearing it out more easily. If the squeal emanates fromunderneath the hood, then it is highly probable that the drive belt is either loose or damaged and it will need to be replaced. Belts are in essence supposed to run for up to 50, 000 miles but if signs of wear are observed then it is advisable to replace it.
