endless flat drive belt

A serpentine belt is a long, winding belt that drives multiple peripheral devices in an engine, including the alternator, power steering pump, water pump, air conditioning compressor, and sometimes even the turbocharger. In the case of the LB7 engine, this single belt is designed to streamline the connection between the engine’s crankshaft and various components, ensuring their effective operation. Unlike older vehicles that have multiple belts for different accessories, a serpentine belt simplifies the layout and reduces the overall weight of the engine.

Like any other component, the fan belt requires regular maintenance to ensure it remains in good working order. Over time, exposure to heat, friction, and environmental elements can lead to wear and tear. Common signs of a worn fan belt include cracking, fraying, or a squealing noise when the engine is running. If left unchecked, a deteriorated fan belt can lead to complete failure, which may cause significant engine damage or a breakdown on the road.
