The Serpentine Belt Should be Inspected
A serpentine belt is a belt that runs through all major components of the vehicle. It transfers power through pulleys from the crankshaft of the engine. It also transfers power from any other component or pump that is mounted on the engine of the vehicle. For some vehicles, an idler pulley or a belt tensioner can also guide the serpentine belt for it to operate efficiently.
One major component that relies completely on the serpentine belt is the alternator. When the alternator on the vehicle is not functioning, the battery cannot be charged. This can result in your vehicle not starting when you will need it. Also, the serpentine belt can affect other components such as the water pump, power steering, fans, and power brakes. If the water pump goes out, this can cause the coolant to stop flowing, which is what helps to protect the engine from overheating and becoming damaged.
You can do a visual inspection of the serpentine belt to see how it is wearing. Noticing any wear can help make you aware for the possible need of the belt being replaced. The serpentine belt may show signs of wear by having more than three or four cracks per inch. If you notice the belt is frayed or missing pieces, the belt should be replaced as soon as possible. If you are not sure of the condition of the belt, make sure to bring the vehicle in so we can inspect it for you.
