What is the fault when the power steering fluid reservoir sprays oil?
3 Answers
The reasons for the power steering fluid reservoir spraying oil: The filter screen of the oil reservoir is clogged, causing poor circulation. Solution: Clear the filter screen. A faulty needle valve can cause oil spraying. Solution: Repair the power steering pump needle valve. There is air trapped in the power steering pump pipeline. Solution: Bleed the air from the pipeline. Power Steering Fluid: It is a special liquid used in the car's power steering pump. Through hydraulic action, it can make the steering wheel very light, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. The role of power steering fluid: Power steering is a new technology in cars that enhances comfort. It automatically provides steering force when the driver turns the wheel, thereby reducing the driver's steering effort. Power steering fluid is a medium oil added to the power steering system, serving to transmit steering force and provide cushioning.
Last time I encountered this issue, I thought about it for a while. The power steering fluid reservoir spraying oil is usually caused by excessive internal pressure in the power steering system or poor sealing. If there are impurities clogging or wear faults when the oil pump is running, it can cause oil pressure to build up with nowhere to release, eventually spraying out from the reservoir opening. Aging or deformed seals on the reservoir can also lead to leaks, especially in hot weather when rubber hardens and is more prone to bursting. Overfilling the fluid or introducing air bubbles during refilling can also trigger similar issues, as the fluid expands when heated and sprays out. If the steering system oil spray is not addressed promptly, the steering will become heavy and sticky, making driving very dangerous and prone to loss of control. It's best to stop the car immediately to check the fluid level and pipe seals, then take it to a professional repair shop as soon as possible for a comprehensive inspection of the oil pump and valves. Don't delay repairs to save money. Regular maintenance, including periodic replacement of power steering fluid and seals, can significantly reduce the occurrence of such failures.
When repairing your car yourself, power steering fluid spraying from the reservoir commonly indicates abnormal oil pressure or seal failure. Excessive pressure may be caused by a clogged power steering pump, blocked oil passages, or air mixed in the fluid that expands and sprays when heated. Aging seals are the most common cause, especially in older vehicles where rubber components deform and leak over time. Start with simple checks: inspect the fluid level in the reservoir - if it's too high, drain and bleed the system, then check for loose or leaking pipe connections. Oil residue buildup indicates seal problems. During repairs, replacing the sealing gasket usually solves the issue. Neglecting this can lead to unstable oil pressure, difficult steering, and increased accident risks. It's recommended to change power steering fluid every two years and clean the pump filter to prevent clogging.
