Power Steering Pump

The power steering pump creates the hydraulic pressure that makes it easier to turn your steering wheel. The pump receives power from the engine via a belt and pulley. As this happens, a number of rotary vanes turn inside the oval-shaped chamber. This draws hydraulic fluid from a reservoir tank. Meanwhile, the engine creates pressure to give you more turning force. Engine speed governs the amount of pressure – and therefore the amount of force – available. The pump applies this force to a piston in the cylinder to help move the wheel in the required direction. Do you hear a whining noise when you turn the steering wheel? Does the power steering seem slower to act than usual? These are both signs of a faulty steering pump.
