How many kilometers should power steering fluid be changed?

[Cinna]

Power steering fluid should be replaced every 40,000-50,000 kilometers or within 2-3 years. Method for changing power steering fluid: When changing the fluid, air needs to be purged from the system during refilling or if air gets mixed into the steering system. The bleeding procedure is as follows: First fill the fluid to the specified level in the reservoir, then start the engine and lift the front axle. With the engine idling, remove the drain plug at the bottom of the steering gear. Turn the steering wheel fully left and right several times, repeating this process while continuously topping up the reservoir. Simultaneously, loosen the system's bleed screw until the fluid fills the entire system with no air bubbles emerging from the bleed port, and the reservoir level stabilizes. Finally, tighten the bleed screw. Precautions for changing power steering fluid: Do not operate the power steering pump for extended periods as this may damage the pump. Never use transmission fluid as a substitute for power steering fluid - these fluids have different viscosities, molecular structures, and functions.
