Power steering fluid circulates within a closed hydraulic system in your vehicle's power steering. It starts in the power steering fluid reservoir, from where a high-pressure hose carries the fluid to the power steering pump. The pump then pushes the fluid to the steering rack or gear, which assists in turning the wheels. After flowing through the steering mechanism, the fluid returns via a low-pressure hose back to the reservoir, completing the cycle as long as the engine is running
. In summary, power steering fluid moves from the reservoir to the pump, then to the steering rack, and finally back to the reservoir, continuously circulating to provide hydraulic assistance and lubrication to the steering system.
