When to Replace Power Steering Fluid?
2 Answers
To determine whether the power steering fluid needs replacement, the most direct method is to assess the steering feel. Power steering fluid is designed to make the steering wheel lighter when the driver turns it. If the steering feels heavier during operation, it is likely due to the deterioration of the power steering fluid, which reduces the effectiveness of the power steering. Relevant information about power steering fluid is as follows: Introduction: Power steering fluid is a special liquid used in the car's power steering pump. Through hydraulic action, it makes the steering wheel very light, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. Classification: The power steering systems installed in cars can be roughly divided into three categories: the first is mechanical hydraulic power steering systems; the second is electro-hydraulic power steering systems; and the third is electric power steering systems.
As a friend who has been driving for fifteen years, I’ll share my experience about power steering fluid replacement. I remember in the third year when my car hit 30,000 kilometers, the steering wheel felt a bit heavy. Upon inspection, I found the power steering fluid had turned black with a slight odd smell, so I immediately replaced it with fresh fluid. After that, the system ran smoothly, and the noise reduced. Generally, it’s recommended to replace the fluid every two years or every 20,000 to 40,000 kilometers, but it also depends on driving conditions. If you frequently deal with city traffic jams and frequent starts, the engine’s constant operation will age the fluid faster. Before replacement, always check the fluid level and color: the reservoir is located in the engine bay—refer to the manual for its exact position. If the fluid is clear, it’s fine; if it’s dark brown or has contaminants, it’s time for a change. Neglecting this can lead to steering pump wear, and repairs can be extremely costly. I’ve made it a habit to quickly check the reservoir’s condition every year to prevent issues. Now, my car has smoothly reached 100,000 kilometers with barely any problems in the power steering system—totally worth it.
