What are the symptoms that indicate power steering fluid needs to be replaced?

If the vehicle's steering wheel becomes heavier, it may indicate a potential leakage of power steering fluid or a decline in performance due to fluid deterioration. In such cases, the power steering fluid should be promptly inspected. If the fluid appears black or contains a significant amount of impurities, it should be replaced (normal power steering fluid typically has a reddish color). Precautions to note: 1. Power steering fluid contains carcinogenic substances; if it comes into contact with the skin, wash it off immediately. 2. The fluid is corrosive and may cause paint to lose its luster or rubber components to deteriorate; if spilled, clean it promptly. 3. For vehicles equipped with hydraulic power steering systems, avoid holding the steering wheel at full lock for extended periods, as this may lead to overheating and damage to the power steering pump.
After driving for several years, I noticed the steering wheel has become particularly heavy, especially when reversing or turning, requiring more effort to turn, as if carrying a heavy load. There's also a buzzing noise during steering, like metal rubbing, which becomes noticeably louder after starting the vehicle. During my last visit to the shop, the mechanic opened the power steering fluid cap and showed me that the originally clear fluid had turned dark brown with some impurities, indicating the fluid had aged. Power steering fluid is responsible for lubricating the steering system, and not changing it for a long time can lead to pump damage, resulting in expensive repairs. I delayed it for a few months, and as a result, the steering pump noise became louder and almost failed. Based on experience, the fluid should be checked and replaced every two years or 50,000 kilometers, before symptoms worsen. Regularly monitor the fluid level; if it's low, top it up, but if the color is abnormal, it's necessary to replace it entirely.
