What is a power steering fluid reservoir?
A power steering fluid reservoir is an essential part of most hydraulic power steering systems
. It’s a small container that holds the system’s hydraulic or power steering fluid. The system uses this fluid to reduce the amount of force necessary to move the steering wheel. The reservoir is usually plastic and typically has two hoses: a return line and a supply line. The high-pressure supply line feeds fluid to the power steering pump. Once the fluid travels through the power steering rack and pinion, it returns to the reservoir via the low-pressure return line.
The reservoir serves as a supply and storage unit, ensuring a steady flow of fluid to the power steering pump and the entire system.
When should I replace the power steering fluid reservoir on my car?
There is no set replacement interval for the power steering fluid reservoir. That means that you’ll only need to replace yours if it fails. Here are the most common signs that you may have a bad power steering fluid reservoir:
Power steering fluid leaks: One of the top signs of a faulty power steering fluid reservoir is fluid leaks. If you notice dark red liquid in the engine bay or beneath your car, you may have a bad reservoir.
Difficulty steering: If the power steering fluid reservoir is leaking or contaminated, you’ll likely notice it becomes increasingly difficult to turn the steering wheel.
Noises while turning: Another common sign of power steering problems is hearing strange noises while turning the wheel. You may notice groaning or squealing noises, especially when turning the wheel far in one direction.
Keep in mind: These issues can indicate other problems, like a bad power steering pump, low power steering fluid, a worn-out accessory pulley, or even a bad serpentine belt. The best way to correctly identify your problem is to visit a certified mechanic for an accurate diagnosis.
How often should I replace my power steering fluid reservoir?
There is no fixed replacement schedule for the power steering fluid reservoir. Instead, you’ll need to replace it only when it begins displaying signs of failure. The most common symptoms of a faulty reservoir include fluid leaks, trouble steering, and fluid contamination.
Can I replace my power steering fluid reservoir myself?
A power steering fluid reservoir replacement generally requires mid-level automotive repair skills and access to basic tools. It can make a solid DIY project for experienced hobbyists and home mechanics, but novices may find it too complex. If you’re uncomfortable performing the repair yourself, you should seek help from a professional mechanic.
