To perform the several functions of the internal combustion engine, the car has numerous accessories and components. All the accessories of the car have their own stipulated functionality and working principles. But the reality behind is, all of the components are not function properly without a properly functioning serpentine belt. Through the help of the idler pulley and belt tensioner, the serpentine belt is running smoothly.

On the other hand, the serpentine belt is also known as an accessory belt or engine belt because it is the main component of the engine that can be visible when you open up the car hood. Moreover, these belts are easily recognizable due to their distinct ridges that can be running the length of the belt on one side. So, when you are turning the accessory pulley, the ridges of the serpentine belt can maintain its grip.

Eventually, you will notice that the alternator is not charging and dead the parts that are running through the electricity such as radio, spark plugs, and headlights. As a result, the battery is dead and shows the snapped belt issues.
