Power steering fluid is a hydraulic fluid used to assist in the steering of vehicles. It is typically a red or clear fluid that is pumped through a hydraulic system to provide power to the steering gear. When the steering wheel is turned, the power steering fluid is pressurized and sent to the steering gear, which then uses the fluid pressure to turn the wheels.
Power steering fluid is essential for the safe and efficient operation of a vehicle. It helps to reduce the effort required to steer the vehicle, making it easier to maneuver, especially at low speeds or when parking. Additionally, power steering fluid helps to lubricate the steering system components, reducing wear and tear and extending the life of the system.
