What does a power steering air control valve do?
The power steering control valve directs fluid where to go when you turn the steering wheel. For example, when you turn the wheel to the right, the power steering control valve rotates so pressure is applied to the correct side of the cylinder, so your vehicle goes in the right direction.
Why is a pressure control valve necessary on a power steering pump?
The pump contains a pressure-relief valve to make sure that the pressure does not get too high, especially at high engine speeds when so much fluid is being pumped.
Where is the power steering control valve located?
Once your left front tire has been removed, you should see the power steering control valve. It’s usually attached to the center pitman arm, right above the steering box.
How do you know if your power steering has air in it?
A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.

It’s possible the whining noise is simply coming from trapped air bubbles in your power steering fluid. If you suspect this is the case, you can confirm it by removing the cap from the power steering fluid reservoir and checking if any bubbles or froth has formed in it.
How do I get air out of my steering gear system?
START MOTOR AND CARRY OUT AIR VENTING FROM VENT VALVE ON THE DISCHARGE SIDE OF HYDRAULIC CYLINDER WHILE OPEARTING THE STEERING GEAR PORT AND STARBOARD ALTERNATIVELY BY MEANS OF MECHANICAL HANDLE. THIS IS DONE UNTIL AIR BUBBLES ARE COMPLETELY REMOVED.
What causes steering to be hard to turn?
The most common cause of a stiff steering wheel is when you are running low on power steering fluid in your system. Often, this happens when there is a leak in the system from the pressurized hose area. Most of the time, it is due to a cracked or loose hose causing the fluid to leak out.
