Understanding the Subaru Power Steering Pump
The power steering system of a Subaru Impreza is an essential component that enables the driver to maneuver and control the vehicle easily. At the heart of this system is the power steering pump, which plays a crucial role in providing hydraulic assistance to turn the wheels.
Understanding how the Subaru power steering pump works is essential for any Impreza owner. It can help identify potential issues and ensure proper maintenance of this critical component. In this section, we will delve deeper into the function and operation of the power steering pump.
The main job of the power steering pump is to supply pressurised fluid to assist with turning the wheels. Depending on the year and model of your Impreza, it is driven by either a belt or an electric motor. The pump draws fluid from a reservoir and then pumps it through high-pressure hoses to reach the steering gear assembly.
Inside the pump, there are two chambers separated by vanes or pistons. As these components rotate, they create suction while pushing fluid out on the other. This creates pressure in the system, which assists in turning the wheels when you steer.
One key aspect of Subaru’s power steering pumps is their variable-assist feature. This means more pressure is provided for easier turning at low speeds, such as during parking maneuvers. As speed increases, less assistance is needed to optimise fuel efficiency.
Importance of a Functional Power Steering Pump
The power steering pump, including the Subaru Impreza, is a crucial vehicle component. It plays a vital role in helping drivers have better control and handling of their vehicles while on the road. The power steering pump uses hydraulic pressure to assist in turning the wheels, making it easier for drivers to maneuver their cars. Without a functional power steering pump, driving can become complex and dangerous.
One primary reason for having a functional power steering pump is to ensure the driver’s and passengers’ safety. A malfunctioning power steering pump can cause unexpected jerks or stiffness in the steering wheel, making it challenging to control the vehicle’s direction. This can be especially dangerous when driving at high speeds or navigating busy traffic. A properly functioning power steering pump provides smooth and effortless steering, allowing drivers to react quickly and safely.
Moreover, having a functional power steering pump improves the overall driving experience by reducing fatigue. Steering without assistance from a power steering pump can be physically demanding, especially during long drives or on rough roads. With proper hydraulic pressure from the pump, drivers can maintain precise control of their vehicle without exerting excessive effort or strain on their arms and shoulders.
Signs of a Failing Power Steering Pump
The power steering pump is a key component of your Subaru Impreza’s steering system. It provides the necessary hydraulic pressure to assist with turning the wheels. Over time, this pump can begin to fail and may exhibit signs indicating it needs to be replaced. This section will discuss the most common signs of a failing power steering pump so you can identify them early and take action before they cause further damage to your vehicle.
Difficulty Turning the Steering Wheel:
One of the first indications of a failing power steering pump is difficulty turning the steering wheel. As the pump loses efficiency, turning the wheel, especially at low speeds or when parking becomes harder. This can also result in a noticeable decrease in handling and responsiveness while driving.
Whining Noise:
A whining noise from under the hood while you turn or accelerate could indicate that your power steering pump is failing. This noise typically occurs due to air trapped in the system or worn-out bearings within the pump.
Leaking Fluid:
The power steering system relies on fluid to function correctly, and any leaks within it can lead to problems with your power steering pump. If you notice red or brown coloured fluid leaking from underneath your car, it could indicate a leak in either the pump itself or one of its hoses.
Choosing the Right Subaru Forester Power Steering Pump
When it comes to maintaining and repairing your Subaru Impreza’s power steering system, you must pay attention to the power steering pump. This pump is responsible for providing hydraulic pressure to the steering rack and assisting with turning the wheels.
