If you drove any old car that does not have a power steering system, you may have noticed or experienced that steering these cars is very hard even in a stationary position. You just exert a lot of force to turn this steering wheel.

So, with the new power steering applications, most of which are hydraulic systems, you do not need to exert lots of force to steer your wheels or your backup.

If there is a hydraulic power steering system, there is a hydraulic fluid that exerts the hydraulic force on the steering system. This hydraulic fluid, which is also called power steering fluid, is pumped from the steering pump.

Hydraulic steering pump levels must be at a specific level, which is generally specified on the steering pump column under your hood. Take a look at that column or reservoir, and if you notice that the power steering fluid is lower than the specific position, you need to add more.
