Power steering is an essential feature in modern vehicles that provides drivers with the ability to steer their vehicles with minimal effort. The power steering pump is the component responsible for powering this system. This pump is located in the engine bay and is powered by the vehicle’s engine. It uses hydraulic pressure to help turn the wheels, making steering easier and more responsive.
In this article, we will take a closer look at power steering pumps, their functions, how they work, the different types of power steering pumps, and the signs of a failing power steering pump.
Functions of a Power Steering Pump
The primary function of a power steering pump is to provide hydraulic pressure to the power steering system. This hydraulic pressure is created by a belt-driven impeller within the pump that draws power steering fluid from the reservoir and pushes it through the power steering system.
How Does a Power Steering Pump Work?
The power steering pumps for a smooth ride are typically mounted on the engine block and is driven by the engine’s serpentine belt. The pump consists of an impeller, a pump housing, and a pressure relief valve. As the engine turns the pump, it draws power steering fluid from the reservoir and pushes it through the power steering system.
The pressure generated by the pump’s impeller creates hydraulic pressure that is transmitted to the power steering rack or steering box. This pressure helps to reduce the amount of effort needed to steer the vehicle, making it easier and more responsive.
Types of Power Steering Pumps
There are two main types of power steering pumps: hydraulic and electric.
Hydraulic power steering pumps are the most common type and have been used for many years. These pumps use hydraulic pressure to help turn the wheels and require regular maintenance to ensure they are functioning correctly.
Electric power steering pumps, on the other hand, use an electric motor to provide power to the power steering system. These pumps are more efficient than hydraulic pumps and require less maintenance. However, they can be more expensive to replace.
Signs of a Failing Power Steering Pump
There are several signs that your power steering pump may be failing. These include:
Whining Noise: If you hear a whining noise when turning the steering wheel, it could be a sign that the power steering pump is failing.
Difficulty Turning the Steering Wheel: If it feels like the steering wheel is harder to turn than usual, it could be a sign that the power steering pump is not providing enough hydraulic pressure.
Leaking Power Steering Fluid: If you notice power steering fluid leaking from your vehicle, it could be a sign that the power steering pump is failing.
Erratic Steering: If the steering feels erratic or unresponsive, it could be a sign that the power steering pump is not functioning correctly. SuncentAuto is the largest online auto parts store that sells automobile parts and accessories at the best prices all over the globe.
In conclusion, the power steering pump is an essential component of a vehicle’s power steering system. It provides hydraulic pressure that makes steering easier and more responsive. Regular maintenance and inspection can help prevent power steering pump failure and keep your vehicle’s steering system functioning correctly. If you notice any of the signs of a failing power steering pump, it is important to have it inspected and repaired as soon as possible.
