How often should power steering fluid be replaced?
2 Answers
Power steering fluid should be replaced approximately every two years or 40,000 kilometers. Failure to replace it for an extended period can lead to: damage to the power steering pump, heavier steering, reduced steering sensitivity, accelerated wear of the internal gears and racks in the steering gear, and a shortened lifespan of the steering gear. Power steering fluid is a special liquid used in the car's power steering pump, which, through hydraulic action, makes the steering wheel lighter, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. The reasons for power steering failure include: 1. Partial failure of the steering system; 2. Complete failure of the steering system, where the power steering function is no longer effective; 3. The handbrake is not released; 4. The EPS (Electric Power Steering) is not activated; 5. A malfunction in the power steering pump.
I've been driving for over a decade and have some solid experience with power steering fluid changes. Generally, it's recommended to replace it every two years or after driving 50,000 kilometers—just check your vehicle's manual for specifics. If you delay changing the oil for too long, the steering will become heavy and stiff. Last time I got lazy and put it off for half a year, turning the steering wheel felt like a workout! I had to rush to change the fluid before things improved. Don’t just focus on mileage—if you often drive on dusty, rough roads or frequently hit the highway, the fluid gets dirty faster and needs more frequent changes. When replacing the fluid, ask them to check the brake fluid and power steering pump too—it’s better to get full maintenance for peace of mind. Stick to this routine, and your car will run smoothly and safely, saving you from unexpected breakdowns and headaches.
