What Causes Severe Bubbling in the Power Steering Pump Reservoir?
1 Answers
The reason for bubbling in the power steering pump reservoir may be due to excessive oil level, high oil surface, or a clogged oil inlet filter screen, causing oil to churn when returning during steering. Function and characteristics of power steering fluid: Function: Power steering fluid is a medium oil added to the power steering system, serving to transmit steering force and provide cushioning. Characteristics: Power steering fluid, also known as power steering oil, is essentially a type of hydraulic oil. Compared to brake fluid, it has higher viscosity, poorer fluidity, and can corrode the sealing components of the brake system. Method for replacing power steering fluid: Before replacing the power steering fluid, start the car and use an oil extractor to remove all the old fluid, then inject new power steering fluid. Next, turn the steering wheel back and forth to allow the new fluid to permeate, which also helps clean the system. For thorough permeation, it is best to turn the steering wheel sharply left and right first, then make slight left and right turns. However, the purpose of turning the steering wheel back and forth is to expel the old fluid from the steering gear. Avoid holding the steering wheel at full lock for extended periods, as this can cause excessive oil pressure and lead to fluid ejection. Repeat this process three times to ensure all old fluid is completely removed before adding new fluid. Note that the same type of power steering fluid should be used for all three additions, and mixing different types is not allowed.
