Power steering fluid is a hydraulic fluid used in the power steering system of passenger cars and commercial vehicles to transmit force from the steering wheel to the steering gear. Located within the power steering pump, hoses, and steering rack, this fluid enables assisted steering, reducing driver effort. Modern power steering fluids are specifically formulated to prevent corrosion, maintain seal compatibility, and provide consistent performance across a wide temperature range. Different vehicle manufacturers require specific fluid types - typically mineral oil-based, synthetic, or full synthetic - so correct specification is critical for system longevity.
