What causes the sudden loss of power steering fluid?

[DeEllie]

The main reasons for power steering fluid leakage are improper driving by the driver, damage to the power steering pump, or overfilling of the power steering fluid. Replacement cycle for power steering fluid: To prevent the power steering fluid from becoming too dirty or deteriorating, it is recommended to replace the power steering fluid every 2 years or 30,000 kilometers. If the power steering fluid is not replaced for a long time, it can cause damage to the power steering pump and steering gear. Method for replacing power steering fluid: Start the car and use an oil extractor to remove the old fluid completely; inject new power steering fluid and turn the steering wheel back and forth to allow the new fluid to penetrate and clean the system; then remove the fluid from the power steering fluid reservoir and inject new fluid while turning the steering wheel. Precautions when replacing power steering fluid: Do not hold the steering wheel at full lock for too long, as this can cause excessive oil pressure and lead to fluid spraying out; do not mix different types of fluids; and do not run the engine without fluid for an extended period, as this can damage the power steering pump.
