Power steering systems & power steering reservoirs are an essential component of modern vehicles, providing drivers with smooth and intuitive steering. At the heart of this system is the power steering reservoir, a vital part that stores and supplies power steering fluid to ensure optimum performance. In this comprehensive guide, we will take a detailed look at the functions, principle of operation, and common problems faced by power steering reservoir drivers. By the end of this article, you’ll have a better understanding of the power steering reservoir and will be equipped with valuable troubleshooting tips.

What is a Power Steering Reservoir?
The power steering reservoir is a small container, usually made of plastic or metal, that sits near the power steering pump. Its primary function is to store power steering fluid, which is a hydraulic fluid that allows the power steering system to function effectively. The power steering reservoir ensures a constant supply of fluid to the system, allowing for smooth, responsive steering.
How Does a Power Steering Reservoir Work?
The power steering reservoir works in conjunction with the power steering pump to maintain the proper level of fluid in the system. When the driver turns the steering wheel, he activates the power steering pump, which pressurizes the power steering fluid. The pressurized fluid is then sent to the steering gear or rack, allowing the driver to turn the wheels with minimal effort. Excess fluid not used by the steering system is stored in the reservoir until needed.
Where Is Power Steering Reservoir Located?
The power steering reservoir is usually located near the engine compartment, near the power steering pump. This is usually a small plastic or metal container labeled “Power Steering Fluid.” Check your car’s owner’s manual for the exact location of the power steering reservoir in your vehicle.
Power Steering Reservoir with Filter
Some power steering reservoirs come equipped with a built-in filter. The filter is designed to trap contaminants and debris in the power steering fluid. Over time, these contaminants can build up and affect the performance of the power steering system. The filter prevents these particles from circulating in the system, ensuring smooth operation and increased component longevity.
Power Steering Reservoir and Pump
The power steering pump and reservoir work together as an integral part of the power steering system. The pump draws power steering fluid from the reservoir and pressurizes it to assist in steering. It then sends the pressurized fluid through hoses to the steering gear or rack, allowing the wheels to turn smoothly. Pump efficiency and functionality are critical to trouble-free operation, making regular maintenance and timely replacement crucial.
What Power Steering Fluid Do I Need?
The type of power steering fluid you need depends on the specifications of your vehicle. You need to consult your car’s owner’s manual to find the recommended type of power steering fluid and ensure compatibility.
Can Power Steering Fluid Freeze?
Yes, power steering fluid can freeze, especially in extremely cold temperatures. When the fluid freezes, it becomes less effective in providing hydraulic support to the steering system. This can cause steering to become stiff and difficult, making the vehicle difficult to control. To prevent the fluid from freezing, it is critical to use the proper type of power steering fluid for your vehicle’s operating conditions.
Faulty Power Steering Fluid Can Result In ?
- Stiff Steering: If your power steering fluid is low or contaminated, it can cause stiff steering, requiring more effort to turn the steering wheel.
- Noisy steering: Contaminated or air-filled power steering fluid can cause a hissing or whining sound when you turn the steering wheel.
- Leaking Fluid: A damaged power steering reservoir or hose can cause fluid to leak, which can cause a gradual loss of power steering assist.
- Inconsistent Steering: Improper or inaccurate power steering fluid can cause the steering to feel unpredictable or unstable.
- Premature Wear of Components: Dirty or contaminated power steering fluid can increase wear of power steering components, which can result in costly repairs.
When Is Power Steering Fluid Low?
Signs of low power steering fluid in your vehicle’s power steering system may be symptoms such as difficulty turning, a whirring sound when you turn the steering wheel, or a screeching noise when the engine is running. If you experience any of these problems it is imperative that you check the power steering fluid level immediately.
When Does Power Steering Fluid Need to Be Changed
The power steering fluid should be changed according to the manufacturer’s recommended maintenance schedule. It’s generally recommended to change your power steering fluid every 30,000 to 60,000 miles, but it’s necessary to check your car’s specific service interval.
Power Steering Fluid Not Circulating
When power steering fluid is not circulating properly, it can lead to a lack of power steering assist and possible steering problems. Several factors can cause poor fluid circulation, including air bubbles in the system, a clogged filter, or a faulty power steering pump.
Power Steering Reservoir Is Bubbling
A bubbling power steering reservoir may indicate aeration in the system. Air bubbles can impede the smooth flow of fluid and cause foamy or aerated power steering fluid. This could be due to a low fluid level, a leak in the system, or a bad pump.
Power Steering Fluid Is Foamy
Foamy power steering fluid is a sign of aeration in the system, where air is trapped in the fluid. This can affect the fluid’s ability to effectively provide hydraulic assistance, which can affect steering performance. Regular maintenance and treatment of leaking or damaged components can help prevent foaming of the power steering fluid.
Power Steering Fluid Is Black
Black or dark colored power steering fluid is a sign of contamination and the presence of debris in the system. This can be caused by worn seals, hoses or power steering pump components. If the fluid appears black, it is necessary to flush and replace it to prevent further damage to the power steering system.
Bottom Line
The power steering reservoir plays an important role in ensuring smooth and comfortable steering for your vehicle. Understanding their functions and common problems can help you identify and remedy potential problems early, ensuring the longevity and reliability of your power steering system. Regular maintenance, selection of proper fluid and timely repairs are the keys to a safe and comfortable driving experience with optimum power steering performance.
