4pk belt

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.

A fan belt adjuster, commonly referred to as a tensioner, is a device that maintains the proper tension on the fan belt. It ensures that the belt remains adequately tight to prevent slippage during operation. Proper tension is essential not only for the optimal performance of the accessories powered by the belt but also for the longevity of the belt itself. If the fan belt is too loose, it can slip off the pulleys, leading to a complete failure of accessory operations, while a belt that is too tight can cause excessive wear on both the belt and the components it drives.
