flat belt material

The serpentine belt is designed to drive several peripheral devices in the engine, including the alternator, power steering pump, water pump, air conditioning compressor, and more. Unlike the older vehicles that used multiple belts to connect these components, the serpentine belt provides a single, continuous loop that simplifies the design and improves reliability. The design was introduced to reduce engine noise and minimize the chances of belt failure.

The belt connects the crankshaft, which is responsible for converting linear motion from the pistons into rotational motion, to the camshaft, which controls the opening and closing of the engine's valves. During operation, as the crankshaft spins, the timing belt rotates, in turn spinning the camshaft. This precise timing means that as the pistons move down to draw in air and fuel, the camshaft opens the valves at exactly the right moment. If this synchronization is off, the engine may not operate efficiently, leading to performance issues or, in extreme cases, severe engine damage.
