How Often Should the Power Steering Fluid in a Sedan Be Changed?
2 Answers
Sedan power steering fluid should be changed every 40,000 to 50,000 kilometers or every 2 to 3 years. Power steering fluid, also known as steering assist fluid, is the oil used in the power steering system, primarily to assist in steering. Here are some precautions when handling power steering fluid: 1. Power steering fluid contains carcinogenic substances. If it comes into contact with the skin, it should be washed off promptly. 2. Power steering fluid is corrosive and may cause paint to lose its luster or rubber components to deteriorate. If spilled, it should be cleaned immediately. 3. For vehicles equipped with hydraulic power steering systems, avoid holding the steering wheel at full lock for extended periods, as this can damage the power steering pump.
I generally recommend changing the power steering fluid in sedans every 30,000 to 50,000 kilometers or every 2 to 3 years, depending on your vehicle's manual, as different car brands may have variations. Power steering fluid is used to lubricate the power assist system. Over time, the fluid can deteriorate and accumulate impurities, leading to heavier steering or even damage to the power steering pump. If you frequently drive in congested urban areas with sharp turns, the fluid may degrade faster, requiring more frequent changes. If you mostly drive smoothly on highways, the interval can be slightly longer. Neglecting to change the fluid can cause the steering wheel to lock up or lead to accidents, resulting in costly and dangerous repairs. I've seen owners save on this small expense only to end up spending thousands to replace the entire system—it's just not worth it. During maintenance, check the fluid level and color; if it's clear, it's fine, but if it's dark, it's time for a change. Developing this habit ensures safer and more comfortable driving.
