    When to Replace the Power Steering Pump – Signs & Symptoms

    About the power steering pump:power-steering-pump2

    Your car’s power steering system allows for smoother, less “heavy” steering. This allows the car to be controlled with less force. In order for the power steering system to work, hydraulic pressure must be generated. This is what the power steering pump does.

    Powered by your engine’s drive belt, the power steering pump contains several retractable vanes that spin inside a small chamber. As the vanes rotate, they pull power steering fluid through the hoses and increase its pressure. The power steering system then controls this pressure,  allowing for an increased response from the steering wheel.

    When should the power steering pump be replaced?

    Power steering pumps are not part of most car maintenance schedules. This means that they do not require periodic replacement unless they break. In theory, a power steering pump can last the life of your vehicle, however, they generally don’t last longer than 200,000km. 

    When the power steering pump fails, it can cause a leak which can deplete the system of power steering fluid. It can also stop the fluid from being pumped, resulting in stiffer, harsher steering.

    Please Note – the power steering pump is checked for a Warrant of Fitness as correct steering operation in vital for safe driving. Therefore if the power steering drive belt or the power steering pump or power steering hoses are damaged or leaking then any of these will cause your vehicle to fail a Warrant of Fitness (WOF).


    Symptoms of a broken power steering pump:

    When the power steering pump fails, you may notice the following symptoms:

    • Whining noises – If you hear a whining noise when you turn left or right, the power steering pump is the most likely culprit. This wining noise is usually caused by a leak or a lack of power steering fluid being delivered to the power steering pump.
    • Stiff steering wheel – When the power steering pump fails, the steering wheel will become more difficult to move.
    • Squealing noise upon starting the car – A bad power steering pump can lead to the belt coming loose. This will create a loud squealing noise which can be noticed when the car starts or when turning.
