The power steering pump is at the heart of the modern steering system. For more comfort and better control at the wheel, replace your faulty power steering pump at Car Parts 4 Less.

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. To find the correct pump for your car, please enter your licence number in the yellow registration box on the left.
