Although power steering is a typical vehicle feature today, this was not always the case.
More than 50 years ago, power steering was considered a luxury and only found in premium vehicles.
As time passed, power steering made its way into modern vehicles. Like engine oil lubricates internal components to prevent premature wear, the power steering system requires a lubricant known as an energy steering fluid.
Checking power steering fluid levels and performing flushes at the specified intervals is essential, as running out of or low on traction control fluid could have undesirable consequences.
Have you ever pondered why turning a 5,822-pound Cadillac Escalade with a single finger is so effortless?
It is the product of the brilliant engineering underlying power steering, not your high school athletics career.
Power steering is an electrical or hydraulic technology that offers steering help at low speeds and diminishing assistance as speed increases to improve stability.
It enables you to rapidly and painlessly navigate a parking lot, take easy turns in town, whip the wheel while reverse parking, and avoid driving off a cliff at Utah’s 80 mph speed limit.
Power steering fluid inspection and replacement is a crucial component of routine vehicle maintenance on hydro-power steering vehicles.
No worries if you don’t know what that means or are hesitant to complete the assignment independently.
The Drive has compiled a tutorial on how to inspect your system, check your fluid, cleanse your fluid, and be safe during the process. Let’s go!
What Did Power Steering Fluid Do?
Power steering fluid is crucial to the steering assistance procedure. The power steering pump pumps fluid under hydrostatic fluid, allowing the steering gear’s piston to move and lowering the effort required to turn the wheel.
Depending on the wheel’s direction, the rotary check valve applies pressure to the piston and releases it from the opposite side.
As pressure increases, the piston moves, and the vehicle is turned in the intended way.
Modern systems are so intelligent that they can detect the vehicle’s speed and reduce the input from the steering wheel to the steering system, lessening the sensitivity at faster speeds to prevent rollovers and other accidents.
Because traction control fluid is a dynamic fluid required to create steering aid, it generates tremendous heat under extreme pressure.

And because the majority of power steering lack filtering, the fluid eventually becomes polluted with dirt, debris, and power steering components that have deteriorated.
Every 30,000 miles, power steering flushes should be done to keep system components lubricated and to prevent system failure.
Avoiding this maintenance may throw unnecessary strain on the pump, causing it to work harder and possibly accelerate its deterioration.
Between flushes, make sure to monitor the fluid levels. How do you know when to check the levels of the power steering?
Most trustworthy repair providers will inspect fluid levels during each oil change. Nonetheless, you can check for yourself at any time.
How To Check Power Steering Fluid Without A Dipstick?
Follow our instructions for checking the power steering fluids in your vehicle. The optimum time to inspect this fluid is after the vehicle has been operating for a few minutes and has had a chance to warm up. Verify levels with the engine turned off.
- Find the power steering reservoir, verify that it contains power steering fluid by examining the cap’s label, then remove the cap.
- If the tank is made of transparent plastic, the full and empty indicators on the exterior will reflect the current fluid level. If the reservoir is made of metal or is difficult to read, use the dipstick (typically located on the bottom of the cap) to determine the level. The dipstick features lines that indicate whether the fluid level is high, low, or normal.
- If your power steering fluid is low, you will quickly recognize something is wrong. Frequently, your car will exhibit symptoms such as noisy driving, jerky feeling, and steering problems. Check your fluid levels if you observe alterations in:
Sound: The steering process is relatively silent. Whenever you hear noises like shrieking or groaning, something may be wrong.
Even simple motions at a standstill, such as moving the wheels from side to side, generate a terrible noise.
Touch: You may feel jittery as you attempt to change directions. Typically, this is most apparent when the vehicle is going slowly or not at all.
As the power steering fluid is low, the system struggles to function effectively, resulting in a jerky sensation.
Turning difficulty or stiffness is another strong indication that anything is wrong.

Sight: You observe pools or spots under the vehicle where the ground was once dry and devoid of fluid leaks. However, power steering fluid can spill from the pump, steering gear, and pressure lines.
The Drive’s Garage Guide To Flushing Steering Fluid
Follow these simple procedures to flush your power steering system yourself.
- You must park the vehicle on a level surface since you will need to jack it up for flushing, and safe jacking requires a stable vehicle on a level surface. Your garage is an ideal location for this endeavor. If you do not have a garage, look for a level land area.
- Under the hood, a steering column is located on the driver’s side. There should be a long hose nearby that contains the power steering liquid. At the top of this assembly is a filter that must be removed.
- Removing the overflow tank from the radiator will facilitate access to the power steering component. Using it, remove the assembly’s reservoir hose.
- After completing the preparatory steps, you must eventually jack up the vehicle for flushing and refilling. Set the emergency brake and elevate the vehicle using a floor jack. Set the jack to the height you can easily get beneath the vehicle and perform the flushing without difficulty. Use jack stands for enhanced safety.
- Replace the existing fluid in the reservoir with fresh fluid. Use a funnel to facilitate pouring. When this occurs, old fluid will exit the hose’s open end. Place a drip pan there to collect the contaminated liquids. Hold the steering wheel and then slightly rock it back and forth. This action will cause old fluid to exit the reservoir through this hose. Keep turning the wheel until every last drop of old fluid drained from the system.
- When the old fluid has been flushed, and the new fluid has begun to flow, connect the hose’s free end to its assigned location in the power steering unit. Reinstall the overflow tank of the radiator. Refill the steering reservoir with new fluid and install a replacement filter. Utilize paper towels to absorb all unnecessary liquids. Reduce the vehicle’s height and remove the jack and supports. This is how the power steering fluid should be flushed.
What Is A Power Steering Fluid?
Power steering liquid is the hydraulic fluid in a traction control system that delivers power. The fluid under pressure reduces the effort necessary to turn the steering wheel.
