How much power steering fluid do I need?

Power steering fluid is a very crucial part of the whole power steering mechanism. It plays a great role in making the mechanism work smoothly. Moreover, it keeps the components lubricated to avoid any trouble. It is pretty simple to know about all the ins and outs of power steering fluid. Especially, when it comes to the quantity of fluid, it is pretty easy to understand and get used to.

In today’s article, I will take you over to the details about how much power steering fluid do you need. I will try to add all the relevant information for better enlightenment. So, let’s get started! 

How Much Power Steering Fluid Do I Need

About Power Steering Fluid

Let’s first know what the power steering fluid is. So, to make life easier and vanish away all the grind of turning the power steering with force, a mechanism was built. In that mechanism, you turn the steering with less force while the hydraulic system provides a larger force and thus makes the phenomenon work.

So, there comes the steering fluid that makes this whole process possible. So, you can see that the steering fluid has quite a significance.

Signs that You are Low on Steering Fluid

When we are discussing the fluid levels, I think that you should also know about the low-level indication of fluid for good maintenance of your power steering system. Here are the 4 indications that you should remember.

Signs that You are Low on Steering Fluid

Turning Gets Hard

The turning of your vehicle will eventually get harder when the level of steering fluid is low. You will feel great difficulty in turning your car. Remember that when the turning gets harder, it becomes more difficult to handle the power steering than the manual steering. So, if you observe such an issue, inspect the power steering fluid.

Vibrating Steering Wheel

Another important indication is related to the vibrating of the steering wheel. The steering wheel of your vehicle will start vibrating. Thus, a quick inspection is necessary to know what’s wrong. 


You will have unwanted noises like whining and squealing whenever you turn the wheels. The major reason behind this can be low steering fluid. So, whenever you observe this, you should check the steering fluid level right away.


Another sign of a low level of fluid is leakage. If you observe any leakage under your car and you identify the color of the fluid (if it seems like steering fluid), then you should get the system inspected by some expert. Otherwise, you may come across bad consequences.

Locating the Reservoir

Once you observe a sign of low power steering fluid, it is time to locate the reservoir. If you haven’t ever done it before, then do not worry. I will tell you how to locate the power steering fluid reservoir. It is pretty easy. 

You have to look for all the fluid reservoirs first. Then you have to go for the cap. The cap of the steering fluid reservoir is generally marked with the steering wheel. It either seems like a steering wheel or you will see a circle with two curved lines. If we get more specific, the cap would be black with a yellow sign on it.

1. How to Check Power Steering Fluid?

The process is pretty simple. You have to follow the steps below and you will know how to check the fluid level.

  • First off, locate the reservoir as I told you how to do it.
  • (Note that a lot of vehicles have their steering fluid tank marked. There are MAX and MIN markings on the tank usually. That can help you see the level quite easily).
  • If there are no markings, then go for the dipstick. Take out the dipstick and clean it. Now, put the dipstick back to see the level of the fluid. Remember that you have to use the correct referencing. It is according to the temperature of the engine.
  • If you are low on steering fluid, fill it up to an appropriate level.

2. How Much Power Steering Fluid Do I Need?

The power steering fluid level is not a standard. Rather, it varies from vehicle to vehicle. Moreover, the manufacturers recommend some levels that should be followed. But the process can get tedious, and you should know about the appropriate levels overall.

Also, as I mentioned before, there are multiple ways to know the fluid level. Either the reservoir will have markings, or the dipstick will help you know the level. 

But when we talk about the temperature conditions, we should be aware of the fact that the fluid has a lower volume when cold while a greater level when warm. 

So, we have two conditions here. Either the engine is running (warm fluid) or it is not (cold fluid).

If you fill the reservoir under cold conditions and turn ON the engine, the oil may expand and get out to spill.

To deal with this situation, you should fill the fluid to MIN level and then turn the engine ON. You should now observe the rise in the fluid level when the car is warmed up. 

Now, you can add more fluid to reach a suitable level near the MAX position. But all this process is in case you do not have hot or cold markings.

If your vehicle offers cold and hot markings, then that is pretty useful. In that scenario, all you have to do is fill the reservoir in a certain temperature condition.

Like, you can fill up to MAX position depending on if the engine is ON or not. If it is OFF and the vehicle is cold, then you will fill MAX according to the cold marking.

On the other hand, if the engine is ON and the fluid is warm. You will fill it to the MAX position with respect to the warm markings.

You should always do the filling by setting your car in an idle position and turning the steering wheel full lock to the left and right. The new fluid will get pumped this way and the level will be achieved correctly.

Frequency of Fluid Replacement

It depends on what your manufacturer has recommended. Otherwise, if the fluid seems dark in color, that means it should be replaced now. Also, the general time for fluid replacement is around 2 years. Make sure about yours. Also, remember that you have to flush the tank as well before adding the new fluid for good performance.

Should You Change Power Steering Fluid in Your Car?

Frequently Asked Questions 

Here are some frequently asked questions to answer your general queries.

1. What if I do not fill enough power steering fluid?

Not filling up to an appropriate level can lead to some bad consequences. The first effect of that is pump damage. Low steering fluid can damage the pump. Moreover, there will be wear and tear due to the low amount of fluid and corresponding friction.

2. What if I overfill the power steering fluid?

This does not affect your vehicle or steering system directly, but it can surely make a mess. Like, excessive fluid will expand, and it can get leaked. Thus, there will be fluid spillage and the spilled oil can affect other parts.

3. What power steering fluid should I buy?

This is not fixed. Like you can not just buy some random steering fluid and pour it into the reservoir. There are manufacturers’ recommended fluids that should be your first priority. So, first, look for the manual and see what is recommended by the manufacturer. If you can not find it, then you should find some experts for suggestions based on your vehicle.

4. Is it bad to drive with less power steering fluid?

Power steering fluid has an important role to play. So, you should not drive with less power steering fluid. Some common damages include pump damage, wear and tear, and excessive friction. Moreover, you will feel hard steering due to less steering fluid.

5. Can you add more power steering fluid without flushing?

Flushing is recommended if the fluid is in a bad condition. Because over time, contaminants can make the fluid dark. If the reservoir is low on fluid and the fluid is in a bad condition, then you should flush the fluid first and then add the new. If it is not in a bad condition, then you can add more but do not overfill it.

Wrapping Up

I have tried to equip you with all the necessary knowledge related to power steering fluid level and quantity. You should keep everything in mind if you are looking for a healthy power steering system. Keep checking the reservoir and system at regular intervals. I would recommend you get it checked every time you go for tuning and service. Do not bypass the instructions because that can lead to additional problems. 

I hope you are all demystified about the topic by now. You can keep surfing more for extra knowledge. Have a wonderful day!
