What Is A Power Steering Pump, And Why Is It Important?
Driving a car is a process made easier by the introduction of power steering. Not only does it contribute to a smoother drive, but it makes it easy to maneuver your vehicle through tight spots like parking lots at low speeds. When your power steering goes out, it feels all but impossible to turn the wheel. The light feel that lets you turn the wheel with one hand becomes a wrestling match just to manage a slight turn.
That's why we're covering the power steering pump and why it's important. We'll also cover the types of power steering, where the pump is located, and how long it should last. Finally, we'll let you know the best place to buy a power steering pump for your Toyota car or truck.
What Is A Power Steering Pump?
At its core, a power steering pump is a mechanical device designed to assist the driver by minimizing the effort needed to turn the steering wheel. It is an integral part of the power steering system, which have become standard in modern vehicles. Without a power steering pump, turning the steering wheel would be a physically demanding task, especially at low speeds or when the vehicle is stationary. There are two types of power steering systems - hydraulic and electrical.
Hydraulic Power Steering
The most common form of power steering is hydraulic power steering, which uses a pump to provide hydraulic assistance to the steering gear that connects the steering wheel to the front suspension and, ultimately, the front wheels. This pump is powered by a serpentine belt off the engine's crankshaft pulley, which pressurizes the hydraulic fluid and reduces steering effort.
Electric Power Steering
More recently, electric power steering has increasingly replaced hydraulic systems. In an electric-assist system, the hydraulic pump and all of the hydraulic components are replaced by an electronic motor and sensors that vary the level of power assist. The benefits of an electric power steering system are reduced weight and reduced power loss from the engine. Additionally, the electric system can be "tuned" for various conditions and to enhance driver feel.
Location Of The Power Steering Pump

The power steering pump is typically located at the front of the engine near the serpentine belt on hydraulic systems. It's easy to locate because the hydraulic pump also has a fluid reservoir to store hydraulic fluid, which connects to the steering gears via power steering hoses.
Most electric power steering systems do not have a pump near the serpentine belt. Instead, they have an electric motor mounted near the steering gears to provide the power assist. The electric system also does not require hydraulic fluid or a fluid reservoir because the operation is entirely electric.
How Long Should A Power Steering Pump Last?
Like many automotive components, the lifespan of a power steering pump can vary depending on factors such as driving conditions, maintenance, and the quality of the pump itself. On average, a power steering pump can last anywhere from 70,000 to 100,000 miles or more. Regular maintenance, including checking and changing the power steering fluid as recommended by the vehicle manufacturer, can help extend the pump's lifespan.
