5 rib serpentine belt

The steering belt, often referred to as the power steering belt, is an essential part of the power steering system. This belt connects the engine's power steering pump to the engine itself. The primary function of this belt is to transfer power from the engine to the pump, allowing for the proper functioning of the power steering system. While modern vehicles may employ electric steering systems that do not use belts, the majority of older and some newer models still rely on hydraulic power steering, making the steering belt an indispensable component.

Power steering systems have evolved significantly since their inception. The introduction of hydraulic power steering systems revolutionized vehicle handling, providing drivers with a level of ease that was previously unattainable. The power steering belt is intrinsic to this system, as it directly affects the pump’s ability to provide the necessary hydraulic pressure to aid in steering. Without a properly functioning power steering belt, the power steering pump cannot operate efficiently, leading to stiff steering and a decrease in maneuverability.
