It is not normal for power steering fluid to boil. Here are detailed explanations about power steering fluid: 1. Definition: Power steering fluid is a medium oil filled in the power steering system, which serves to transmit steering force and provide cushioning, making the steering wheel easier to turn. To prevent the power steering fluid from becoming too dirty or deteriorating, it should be replaced every two years. 2. Precautions: For vehicles equipped with hydraulic power steering systems, avoid turning the steering wheel to its extreme limit during use. Holding the steering wheel at full lock for extended periods can cause damage to the power steering pump. Deteriorated power steering fluid has reduced lubrication capability, which can lead to accelerated wear of mechanical components.

As an experienced driver who has gone through multiple car repairs, I think power steering fluid boiling is absolutely abnormal and a serious issue. The fluid in the system normally operates within a specific temperature range. Once it boils, it indicates overheating. The most common causes are fluid leakage leading to low levels, or a problem with the power steering pump causing it to seize and over-pressurize, rapidly heating the fluid. If not addressed promptly, excessively high fluid temperature can damage pump components, cause seal aging leading to worse leaks, and most dangerously, result in sudden stiffening of the steering wheel with loss of power assistance during turns, which could cause an accident. I recommend immediately stopping to check the fluid reservoir level and color. If it's low or you see bubbles forming, don't drive hastily - contact a professional repair shop immediately to diagnose the root cause. Regular maintenance with proper fluid checks and attention to abnormalities can prevent such crises.

Last time, my car's power steering fluid bubbled and boiled after a long trip, making the steering wheel as heavy as a rock when turning, almost causing me to lose control. After inspection, it was found that too much power steering fluid had leaked, causing the pump to overheat and boil due to lack of lubrication. Later, I spent a few hundred dollars to fix it and replaced the fluid, restoring normal operation. Now, I am very vigilant about power steering system issues: if the fluid reservoir feels scalding hot or there's a squeaking noise, I immediately stop to check if the fluid level is low or if the color is murky. Losing steering assistance while driving is extremely unsafe, especially at high speeds or in rainy conditions where skidding is more likely. For prevention, regularly changing the fluid and cleaning engine compartment dust is very effective—never ignore signs of bubbling fluid as a minor issue.

Friend, if the power steering fluid is boiling like water, it's absolutely not right. Most likely, there's a leak causing low fluid levels, overheating, or the pump struggling under excessive load. Feel the oil pipes with your hand to see if they're unbearably hot, and listen for any abnormal noises from the pump. Drive to a shady spot immediately to cool down—don't push through long distances as steering could become difficult and dangerous. Safety first: stop and check the fluid level; add some if it's low, but avoid amateur repairs to prevent air from entering the system, which complicates things further. Have a shop inspect the pump and lines for wear—simple maintenance can extend the fluid's life and prevent boiling.

Boiling power steering fluid is extremely hazardous and can easily lead to power assist failure, doubling the danger of a stiff steering wheel, especially after traffic jams or heavy loads. System overheating may be caused by poor circulation, low fluid levels, leaks, or pump failure—stop immediately. Check the fluid reservoir; if it's below the MIN line, appears cloudy, or has bubbles, do not continue driving as hot fluid loses viscosity. After cooling down, rush for repairs to avoid safety incidents. Prevention requires regular monitoring of fluid condition and periodic replacement with high-quality fluid.
