sprocket and toothed belt

The dynamo belt, typically made of rubber and reinforced with fibers for added durability, connects the crankshaft to the alternator. It turns when the engine is running, allowing the alternator to generate electrical energy necessary for charging the battery and powering electrical components like headlights, radio, air conditioning, and more. In some vehicles, the dynamo belt may also drive other accessories, such as the power steering pump or water pump, making it a multi-functional component in the vehicle’s powertrain.

Maintaining the serpentine belt is essential for the overall health of your vehicle. Over time, the belt may experience wear and tear, leading to symptoms such as squeaking noises from the engine, visible cracks on the belt surface, or issues with the operation of the powered accessories. If a serpentine belt fails, it can lead to the loss of power steering, difficulties in generating electricity for the vehicle, and overheating due to a malfunctioning water pump.
