What do your power steering, water pump, air conditioner, and alternator all have in common with one another? Each and every one of them is driven by a serpentine belt on a contemporary automobile. If this lengthy strip of rubber were to suddenly break while you are driving, you would not only lose all of these driven accessories, but you would also lose the engine itself. This is something that you really want to avoid happening. The serpentine belts that are used now have a lifespan that is at least 50,000 miles long and may last much longer. Nevertheless, doing a short examination every once in a while might help you save a great deal of stress and inconvenience. This is how you can determine whether or not the serpentine belt in your vehicle has worn out. Pay attention and take notes. Because of their age and the amount of usage they get, serpentine belts have a tendency to become quite loud. In point of fact, belt squeak is often one of the first indications that your serpentine belt needs to be replaced. If the serpentine belt in your vehicle makes a squeaking or squealing sound, whether it occurs when the engine is started or on a regular basis, then it is time to do a more comprehensive check. It is tempting to use solutions like belt dressing to cover up the squeal that comes from a serpentine belt; but, doing so might actually make the situation much more difficult. In addition to the fact that you are disregarding one of the several indications that your serpentine belt has a limited lifespan, there are some things that may actually make the condition of the belt worse, making it more likely to fall apart sooner. Examine the symptoms of wear. Generally speaking, serpentine belts have a tendency to wear down gradually, providing you with enough notice. Keep an eye out for glazing on the top of the belt, as well as grooves to check for. Because of the friction that occurs between the belt and the driving pulleys, glazed areas may be left behind. Glazing may be caused by slippage, which can be caused by improper belt alignment or a weak automated serpentine belt tensioner. Check the belt for fraying and cracking on the top and edges of the belt, as well as on the belt ribs. As serpentine belts age, it is not unusual for them to lose material. This is particularly true in cases where there is a problem with the alignment of the belt or with one of the driving pulleys. In order to determine the tension of the serpentine belt, locate the section of the belt that is the longest between the driving pulleys and apply pressure to the center of the belt. In contrast, a serpentine belt that has been worn out may yield by an inch or more, while a brand-new serpentine belt that has been correctly routed should be tight and have less than a half-inch of play available. in the use of a wear gauge In the event that you are working with a serpentine belt that is constructed from ethylene propylene diene monomer, also known as epdm, there is a good probability that you will not observe the conventional indicators of wear and tear that were discussed earlier. Rather, epdm belts have a tendency to wear out in a way that is comparable to that of a vehicle tire. To put it another way, you will discover progressive wear that is difficult to detect with the naked eye. For the purpose of identifying indications of wear and tear on an epdm serpentine belt, a belt wear gauge is a very useful tool. Place the belt wear gauge on the serpentine belt when the engine is turned off. Ensure that the ribs on the gauge are able to fit into the grooves on the belt. After the instrument has been positioned, attempt to rock the gauge back and forth while maintaining a mild pressure on it to keep it in place. If there is very little to no movement at all and the gauge remains securely placed, then the belt still has a significant amount of life remaining in it. You could even see that the tool is resting just a little bit above the surface of the serpentine belt. In the event that the gauge shakes laterally and/or lays fully flat against the serpentine belt, this indicates that the material around the belt has worn down to the point where it should be replaced.
