Power steering offers a whole load of benefits for every driver. First, it offers a smooth turning of the steering wheel without a lot of effort. Without such, you’ll have a hard time turning the wheel and navigating. The thing about power steering is that it’s a system that needs fluid to work. Thus, it can be worrisome if you see such liquid flowing out. So, you may ask:
If the power steering fluid is blowing out of the reservoir, how should you fix it? A power steering fluid that’s blowing out of the reservoir means there’s air in the system. You can fix this issue by taking the air out and stopping more air from getting inside. You can accomplish this by flushing all the fluid out and refilling it.
When the power steering fluid oozes out of the reservoir, it can affect the system’s performance. Thus, it would be best to have it fixed soon, or else it may affect your car’s power steering performance.
In this article, you’ll see an in-depth take on this matter and the probable cause of this issue. Further, you’ll also see a step-by-step process on how you can fix this problem. This way, you will know how to deal with this issue if it ever happens to you.
Without further ado, let’s get into it!

Power Steering Fluid Pushing Out Reservoir: Why Is That?
If your power steering fluid pushes out of the reservoir, it can be due to several issues. First, however, you should look more into these three leading causes of this problem.
Putting too much power steering fluid
The most common reason for spilling power steering fluid is putting too much in the reservoir. You may quickly pour too much fluid into the tank if you can’t see inside it.
If this happens, the fluid may pour out of the tank’s top. It might cause damage to the power steering system and the other vehicle parts.
This issue is more like a human error, and you can prevent it by being careful when putting the fluid.
Trapped air in the system
The fluid might overflow due to air suspended in the power steering system. When the air gets trapped within a system, bubbles develop.
As the bubbles develop, the fluid is forced against them. If there is enough air in the power steering system, this air may push out the steering fluid. Therefore, the power steering fluid would need to be thoroughly cleansed.
This issue can come from a faulty system, which means you need to check other things in the power steering system and not only the reservoir.
Increase in tank pressure
When the pressure in the tank is too intense, the power steering fluid might overflow. A malfunctioning power steering pump is frequently the cause of this.
A belt and pulley linked to the engine drive the pump. There are tiny fins that rotate within this. These fins draw fluid into the power steering system as they rotate.
A mechanism in the pump controls the pressure of the fluid as it travels into the system. When the pump fails, and the pressure rises too high, the result is an overflowing power steering fluid in the reservoir.
How to Fix Power Steering Fluid Blowing Out Reservoir?
If you want to fix the problem, you’ll need to check the cause of the overflow first. However, in most cases, the air bubbles forming inside cause the power steering fluid to overflow.
Thus, you’ll usually want to flush out the power steering fluid to empty the reservoir. This way, you can free up your reservoir from debris and air that helps in forming bubbles.
If you would bring it to a mechanic or technician, he will likely make some adjustments to specific parts in the system. In most cases, he will tighten and replace other parts that may cause problems.
Here are some steps you can follow when fixing a power steering fluid issue:
Find the cause of overflow.
As mentioned earlier, there are three primary reasons why a power steering fluid will overflow.
Out of the three, you’ll less likely have an overflowing power steering fluid due to overfilling the reservoir. However, it’s still something to consider.
The next one would be the air bubbles forming in the reservoir. If you find these bubbles in your reservoir, you’ll want to flush out the entire tank and clean it. The same goes if you think the tank gets an increase in pressure.
Clean the reservoir by flushing all fluid out.
As you flush all the fluid out, you empty the tank and allow the air and the air bubbles inside to get out. As you empty your reservoir, you’ll also want to clean it from any debris or particles that got stuck in it.
Check the parts to make sure the system is working well.
After clearing the reservoir, you’ll want to check the other components of the power steering system. Do it before you refill the reservoir to make sure you won’t have any problems again.
Also, you may consider replacing most of the parts and making adjustments to your system.
If your hoses have suffered substantial wear, for example, you may require new ones.
You should also adjust your steering pump’s nuts, inspect the seals and other components, bleed the lines, and make sure the steering pump is fully charged.
Now, if you did all these things on your own and the issue persists, you may want to have it checked by an expert.
Summary
In a nutshell, an overflowing power steering fluid is an issue that needs a solution right away. There is air in the system if the power steering fluid is flowing out of the tank. You can solve this issue by flushing out the air and preventing additional from entering. This repair may be accomplished by draining out all of the fluid and refilling it.
When you experience this issue, you can check for possible causes such as overfilling the tank with fluid, air bubbles forming in the tank, and increasing tank pressure. Whatever the cause is, you’ll want to clean the whole tank and check the other parts to ensure your power steering system is all good.
