Power steering fluid is crucial for maintaining smooth steering in your vehicle.
Without sufficient fluid, you may experience difficulty steering, which can lead to dangerous driving conditions and potential damage to the power steering system.
In this guide, we will cover how to check, refill, and maintain power steering fluid to keep your vehicle in optimal shape.
ANCEL offers a range of advanced car scanners that can help you identify potential problems in your vehicle, including issues with the power steering system.
Where Does Power Steering Fluid Go
The power steering fluid reservoir is typically located in the engine bay, near the firewall or close to the engine itself. Its exact position varies depending on the make and model of your vehicle.
In most cases, you’ll find it on the passenger side of the engine bay, but it's always best to consult your owner’s manual for the precise location.
The reservoir is usually a small, translucent container with markings indicating fluid levels and often has a cap labeled with a steering wheel icon or the words "Power Steering Fluid."
This makes it easy to identify among the other components under the hood.
In vehicles with Electric Power Steering (EPS) systems, there might not be a fluid reservoir since these systems don’t use hydraulic fluid.
-
Compact Cars and Sedans: You’ll often find the reservoir near the engine, along the passenger-side firewall.
-
SUVs and Trucks: In larger vehicles, it’s generally mounted closer to the front of the engine bay near the drive belts.
-
Electric or Hybrid Vehicles: Some modern vehicles may use an Electric Power Steering (EPS) system, which doesn't require hydraulic fluid. Always refer to your owner’s manual for specifics.

Where to Put Power Steering Fluid
Once you've located the reservoir, here’s how to properly refill the power steering fluid:
-
Check the fluid type: Your vehicle’s owner’s manual will specify the correct type of fluid to use. Using the wrong fluid can damage your system.
-
Clean the area around the cap: Wipe away any dirt or debris to prevent contamination when opening the reservoir.
-
Open the cap carefully: Some reservoirs include a dipstick attached to the cap, which helps you check the fluid level.
-
Pour in the correct fluid: Slowly add the power steering fluid, using a funnel to prevent spills. Keep an eye on the fluid level to avoid overfilling.
-
Replace the cap: Once the reservoir is filled to the appropriate level, securely tighten the cap.
How to Check Power Steering Fluid
Checking the power steering fluid is a simple yet essential part of regular vehicle maintenance. Follow these steps:
-
Turn off the engine: Park the car on a level surface and turn off the engine to allow the fluid to settle.
-
Locate the power steering reservoir: As previously mentioned, check your manual for the exact location.
-
Check the fluid level: If your reservoir is clear, you can check the fluid level by observing the markings on the side. For those with a dipstick, remove it, wipe it clean, reinsert it, and then pull it out again to check the level.
-
Top off the fluid if necessary: If the fluid is below the “MIN” or “LOW” line, refill it to the recommended level.
It’s advisable to check your power steering fluid level at regular intervals, such as during an oil change, or if you notice any strange noises when turning the wheel.
What Color is Power Steering Fluid
The color of power steering fluid is a good indicator of its condition. When fresh, the fluid is usually clear, pink, or red.
However, as it ages and becomes contaminated with dirt and debris, it can darken, turning brown or even black.
Dark, dirty fluid should be replaced, as it can compromise the efficiency of the steering system and may lead to further damage if not addressed.
If you observe metal particles or a gritty texture in the fluid, this could indicate internal wear within the system, such as damage to the pump or steering rack.
In this case, it’s advisable to have the system inspected by a mechanic.
How to Change Power Steering Fluid
If the fluid is old or contaminated, it’s essential to change it to keep your system running smoothly. Here’s how to do it:
-
Lift the vehicle: Use a jack and secure the car with jack stands to lift the front end of your vehicle.
-
Locate the power steering return line: This is usually the low-pressure line connected to the power steering reservoir.
-
Drain the old fluid: Disconnect the return line and let the fluid drain into a pan.
-
Reconnect the line: After the fluid has drained, reconnect the return line securely.
-
Refill the system: Pour in the new power steering fluid, following the manufacturer's specifications.
-
Bleed the system: Turn on the engine and turn the steering wheel from lock to lock several times to ensure the new fluid circulates properly through the system.
-
Check the fluid level: Once the system is bled, recheck the fluid level and top it off if needed.
How to Flush Power Steering Fluid
Flushing the power steering system removes all the old fluid and contaminants to ensure smooth operation. Here's a step-by-step guide on how to perform a flush:
-
Raise the vehicle: Use a jack and jack stands to lift the front of the car.
-
Disconnect the low-pressure return line: Detach the return line from the reservoir and allow the old fluid to drain completely.
-
Turn the steering wheel: While the engine is off, manually turn the steering wheel from side to side to push out any remaining fluid from the system.
-
Reconnect the return line: Once the fluid is drained, securely reconnect the line.
-
Refill the system with new fluid: Add new power steering fluid to the reservoir.
-
Bleed the system: Start the engine and turn the wheel from lock to lock to circulate the new fluid through the entire system.
-
Repeat if necessary: If the fluid coming out during the flush is still dirty, you may need to repeat the process until clean fluid circulates through the system.
Conclusion
Keeping an eye on your power steering fluid is crucial for the smooth operation of your vehicle.
Regularly checking, refilling, and occasionally flushing the fluid will help prevent wear and tear on your steering components.
Proper maintenance not only ensures a safer driving experience but also helps you avoid costly repairs.
Always refer to your owner’s manual for specific recommendations on fluid types and maintenance intervals to ensure your vehicle’s power steering system stays in top condition.
FAQs
Can I use brake fluid in place of power steering fluid?
No, brake fluid should never be used as a substitute for power steering fluid. Brake fluid has different chemical properties and is not designed for use in the power steering system. Using the wrong fluid can cause damage to the seals and other components, leading to system failure. Always use the correct type of power steering fluid specified in your vehicle’s manual.
What happens if I overfill the power steering fluid?
Overfilling the power steering fluid can create excess pressure in the system, which may cause seals to rupture or fluid to leak. In some cases, this can lead to a complete failure of the power steering system. If you accidentally overfill, it’s best to siphon out the excess fluid to avoid potential problems.
Is power steering fluid universal across all vehicles?
No, power steering fluid is not universal. Different vehicles require specific types of fluid based on the design of their power steering systems. Some vehicles may use synthetic power steering fluid, while others use a mineral-based fluid. Always refer to your owner’s manual to ensure you’re using the correct type of fluid for your vehicle.
