How to Check Power Steering Fluid

Power steering fluid is an oil formulated for use in power steering systems; it reduces the effort required to steer a vehicle. The power steering system uses a pump driven by the engine to generate pressure by compressing the fluid.

To check the fluid, there is either a see-through reservoir with maximum and minimum levels clearly marked on the its side, or the fluid reservoir has a dipstick with maximum and minimum marks, which is withdrawn from the reservoir. If the fluid level is low, fluid is added to the reservoir.

If the power steering fluid requires frequent topping up, it may be a sign of leakage from the steering system, which needs to be repaired.
