What is the function of ac belt?

The AC belt, often referred to as the serpentine belt, plays a crucial role in a vehicle's air conditioning system by driving the compressor. This belt is connected to the engine's crankshaft and transfers power to the AC compressor, allowing it to circulate refrigerant and maintain proper cooling. A functioning AC belt is essential for efficient air conditioning performance; if it wears out or breaks, the AC system will not operate effectively.
