It’s a common question, can I use antifreeze for power steering fluid? The answer is technically yes, you can use it as a stop-gap measure in an emergency. However, it’s not recommended as a long-term solution and here’s why.
Antifreeze is designed to lower the freezing point of water to prevent engine freeze-ups in cold weather. Power steering fluid, on the other hand, is designed to maintain its viscosity at high temperatures so that it can do its job of lubricating and cooling the power steering system components.
- Check your power steering fluid level and add more if needed
- Pour in the anti freeze fluid until the reservoir is full
- Start up your engine and turn the steering wheel from side to side to circulate the new fluid
- Check for leaks and top off the reservoir as needed

What Happens If You Put Antifreeze in Your Power Steering Fluid?
If you put antifreeze in your power steering fluid, it will mix with the fluid and could potentially cause damage to your car’s engine. Antifreeze is a corrosive substance and can eat away at metal, so it’s important to be careful when using it. If you do accidentally put antifreeze in your power steering fluid, flush the system immediately and replace the fluid.
What Can I Substitute for Power Steering Fluid?
If your car’s power steering fluid is low, you may need to add some. But what if you’re out of power steering fluid? Can you substitute something else?
The short answer is no. Power steering fluid is specifically designed to work with your car’s power steering system. It has the right properties to ensure that the system operates smoothly and efficiently.
There are other fluids that may look similar to power steering fluid, but they’re not going to be compatible with your car. Using the wrong type of fluid can damage your power steering system and may void your warranty. So, if you’re out of power steering fluid, head to your local auto parts store and pick up a bottle of the correct type for your car.
In the meantime, check your owner’s manual for more information on how to check and add power steering fluid.
Is Power Steering Fluid the Same As Coolant?
No, power steering fluid and coolant are not the same. Power steering fluid is a hydraulic fluid that helps to transmit the force from the steering wheel to the wheels, while coolant is a liquid mixture used to keep the engine cool.
Can I Use Water Instead of Power Steering Fluid?
No, you cannot use water instead of power steering fluid. Power steering fluid is a hydraulic fluid that helps transfer power from the steering wheel to the wheels, making it easier to steer the vehicle. Water is not incompressible like power steering fluid and will not work as well in the system.
In addition, water can rust and damage components in the power steering system.

Poured Antifreeze in Power Steering
If you have ever accidentally poured antifreeze into your power steering, you are not alone. It is a common mistake that can happen when topping off fluids under the hood. Here’s what you need to know about fixing this problem.
The first thing to do is remove the battery so that you can access the power steering pump. Once the battery is out, locate the power steering fluid reservoir and drain it completely. Next, flush the system with fresh water and refill it with new power steering fluid.
Be sure to check all of the other fluids under the hood as well, such as engine oil and coolant levels. These may have been affected by the antifreeze spill and will need to be topped off as well. It’s important to get this fixed as soon as possible because driving with antifreeze in your power steering can cause serious damage to your pump and other components.
If you’re unsure of how to do this yourself, take your car to a mechanic or dealership for help.
How to Drain Power Steering Fluid
If your car is making a whining noise when you turn the steering wheel, it may be time to drain the power steering fluid. Although this is a relatively easy process, it’s important to follow the steps carefully to avoid damaging your car. 1. Park your car on a level surface and turn off the engine.
Place a large catch pan under the power steering pump on the driver’s side of the engine bay. 2. Locate the power steering reservoir and unscrew the cap. Some reservoirs have a pressure relief valve that must be depressed before removing the cap.
3. Use a turkey baster or syringe to remove as much fluid from the reservoir as possible. Be careful not to get any dirt or debris in the reservoir when doing this. 4. Disconnect the return hose from the power steering pump and allow all of the fluid to drain into your catch pan.
Once all of the fluid has drained out, reattach the return hose and screw on the cap to the reservoir. +5 Fill up your power steering reservoir with fresh fluid until it reaches The Full line . You can use regular automotive ATF (automatic transmission fluid) for this purpose.

Does Power Steering Fluid Go Through the Radiator
Many vehicles have a power steering fluid reservoir that is attached to the radiator. The radiator provides cooling for the engine and also has a small fan that helps keep the power steering fluid cool. If the vehicle does not have a power steering fluid reservoir, then the fluid will go through the radiator.
The reason for this is because when the engine is running, it creates heat and this can cause the power steering fluid to break down. By going through the radiator, the fluid is cooled and can last longer.
Conclusion
If you’re in a pinch and need to top off your power steering fluid, you can use antifreeze. Just be sure to flush it out afterwards.
