The primary function of the V-belt is to transmit rotational motion from the engine to attached components. When the engine runs, the crankshaft spins, causing the V-belt to turn. This motion transfers power to the connected accessories, allowing them to perform their designated roles. For instance, the alternator relies on the V-belt to generate electricity for the vehicle’s electrical system, while the power steering pump uses it to facilitate smoother steering.
