A poly V belt, often referred to as a multi-rib belt, is designed with several longitudinal ribs on one side and is flat on the other. This design allows the belt to maintain a strong grip while minimizing slip, subsequently improving transmission efficiency. Poly V belts are commonly used in automotive applications, HVAC systems, and various industrial machinery. Their ability to deliver power through compact spaces and operate quietly gives them a significant edge over traditional belts.

The fan belt, also known as the serpentine belt, is a looped strip that drives various peripheral devices in an engine. In MAN trucks, the fan belt connects the engine's crankshaft to the cooling system's fan, helping to regulate engine temperature by facilitating airflow over the radiator. It also powers components like the alternator, power steering pump, and air conditioning compressor, indicating that a well-functioning fan belt is essential for maintaining the operational efficiency of the entire vehicle.
