What are the consequences of not changing the power steering fluid?

The consequences of not changing the power steering fluid are: it can lead to damage to the steering gear and power steering pump. Power steering fluid is a medium oil added to the power steering system, which plays a role in transmitting steering force and cushioning. Long-term use of power steering fluid can cause it to become dirty or deteriorate, and it needs to be replaced approximately every 2 years or 30,000 kilometers. The method for changing the power steering fluid is: 1. Lift the vehicle and engage the handbrake; 2. Disconnect the return pipe; 3. Start the vehicle and turn the steering wheel left and right to drain the old power steering fluid, then add new fluid until the color of the power steering fluid is relatively clean; 4. Follow the reverse steps to reinstall the pipe and add new power steering fluid until the fluid level reaches the maximum mark.
I've been working with cars for many years and have seen too many cases of trouble caused by not changing the power steering fluid. Over time, the fluid deteriorates, its viscosity decreases, and its lubricating effect diminishes, leading to increased friction inside the power steering pump. Eventually, the pump and valves wear out severely, causing a buzzing noise when turning and making the steering feel heavier, as if the steering wheel is stuck to the ground. If left until the system completely fails, the repair costs can be steep—replacing the entire power steering system can easily cost thousands. Worse yet, sudden steering failure on the highway is extremely dangerous and can easily lead to accidents. That's why it's wise to regularly check the fluid level and color and replace it on schedule—after all, driving safety comes first.
