A ribbed belt, also known as a serpentine belt, is a continuous belt with longitudinal grooves running along its length. These grooves enable the belt to grip the pulleys more effectively, reducing slippage and improving power transfer between the engine and various auxiliary components. In modern vehicles, including the W211, ribbed belts are used to drive multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor.

V-belts derive their name from their trapezoidal cross-section, which resembles the letter V. This design allows for effective engagement with pulleys, providing superior grip and minimizing slippage. The belts are characterized by their flexibility, enabling them to bend around pulleys while maintaining strength and durability. Depending on the requirements of a particular vehicle, V-belts can come in various sizes, lengths, and materials to accommodate different systems and performance specifications.
