Genuine Bosch power steering pump
KS00000633

A power steering pump is an integral part of a vehicle's power steering system. Its role is to pump hydraulic fluid from the reservoir into the steering gear, which then helps reduce the effort needed to turn the steering wheel. Without the pump, turning the wheel would be far more difficult, particularly at low speeds or when stationary. By transferring fluid to the steering system, drivers can steer more easily and with greater precision. When the steering wheel is turned, a shaft connected to the pump begins to spin. This activates the pump, which draws in hydraulic fluid from the reservoir. The fluid is then pressurized and sent to the steering gear, which uses it to help move the wheels in the desired direction. The power steering pump operates continuously as long as the engine is running, ensuring that the steering system is always functioning optimally. By enabling smoother, more effortless steering, the power steering pump is critical to the safe operation of a motor vehicle.
