Timing pulleys are cylindrical devices featuring evenly spaced teeth designed to mesh with the teeth of a timing belt. Together, they form a system that prevents slippage and ensures that the driven components rotate in perfect synchronization with the driving component. Unlike traditional v-belts, which rely on friction for operation, timing belts are positively engaged with the pulleys, making them ideal for applications requiring precise timing.

In vehicles without air conditioning, the serpentine belt still fulfills its fundamental role in driving essential engine components. For instance, the alternator remains crucial for generating electrical power to recharge the battery and power the electrical systems in the vehicle. The power steering pump is essential for facilitating easier steering, especially in larger vehicles. Additionally, the water pump is vital for maintaining the cooling system by circulating coolant through the engine.

The primary function of a fan belt is to transfer rotational power from the engine's crankshaft to various engine accessories. This is done through a series of pulleys that the belt winds around, allowing multiple components to operate simultaneously. In modern vehicles, the serpentine belt design has largely replaced traditional V-belts due to its ability to drive multiple accessories with a single belt, which improves efficiency and reduces the weight of the engine compartment.
