What Causes Power Steering Fluid Leakage?
2 Answers
Power steering fluid leakage primarily occurs due to the following reasons: 1. Improper driving by the driver. 2. Damage to the power steering pump. 3. Overfilling of power steering fluid. To prevent the power steering fluid from becoming dirty or deteriorating, it is recommended to replace the power steering fluid every 2 years or 30,000 kilometers. Below are the steps for replacing the power steering fluid: 1. Start the car's engine and use an oil extractor to remove all the old fluid. 2. Inject new power steering fluid and turn the steering wheel back and forth to allow the new fluid to penetrate, which helps in cleaning. 3. Remove the fluid from the power steering reservoir again and inject new fluid while turning the steering wheel.
There are quite a few reasons for power steering fluid leakage. I've found it's usually due to loose pipe connections or aging/cracked sealing rings, where rubber components become brittle and fail under prolonged high temperatures. Corroded or collision-damaged oil pipes can also leak, especially in the front wheel area which is prone to road debris impacts. Another common cause is an improperly tightened fluid reservoir cap, allowing fluid to seep out during driving. If not repaired promptly, the steering system bears extra load, potentially wearing out the power steering pump and increasing repair costs. During every maintenance check, I make it a habit to inspect fluid levels and visually examine the undercarriage for oil stains. Don't delay if you spot a leak - seek professional repair immediately to ensure driving safety and prevent sudden steering stiffness that could lead to accidents.
