By This article will explain why your power-steering fluid appears milky and how you can fix it. Let’s not waste any more time.
What color should the power steering fluid be?
Before I go into the details, let’s first look at what causes your power steering fluids to appear milky or foamy.
Take a look at how the power steering fluid typically looks.
Power-steering liquid can come in amber, clear, pink, or red, depending on the make and model of your vehicle.
It shouldn’t be foamy or milky. If the fluid is any color other than orange or red, it could be a problem with your power steering system.
What makes a power steering fluid look milky?
Let’s examine what causes it to look foamy/milky.
A Milky Power Steering Fluid is usually water or air bubbles that have gotten into your system due to leaks or damaged seals.
What causes power steering fluid to become milky?
According to my experience, several things could cause your power-steering fluid to become milky.
Here are some of the most important:
Leaking pipe in the system:
Air can enter your power steering system if you leak. The fluid will become milky and lose its ability to lubricate.
Bad Seal
A leaking seal in the power steering system will let air and water enter.
If you do this, the fluid will turn milky/foamy. This will make your car more difficult to maneuver around corners.
Cracked Powersteering Reservoir Cap
I’ve seen a cracked reservoir cap for the power steering.
The steering fluid will turn milky/foamy if the reservoir cap has been damaged or broken.
The power steering Pump is Going Bad.
The power steering pump is a vital part of the power steering system.
The system turns the steering wheel easier, especially at low speeds, because it generates hydraulic pressure transmitted to the steering gear.
A rotary valve regulates fluid flow from the hydraulic pump at the vehicle’s speed.
My experience as a mechanic has shown that a power-steering pump is on its way out if it produces foamy or milky fluid.
What Symptoms Could You Experience if Your Power Steering fluid looks milky?
After explaining the causes of milky-looking steering fluid, let’s look at the symptoms you may experience.
The steering feels harder to turn.
When your power steering fluid is milky, it can make the wheel harder to turn.
The fluid’s air bubbles reduce the liquid’s ability to transmit hydraulic force. This means that it takes more effort to turn the wheel than usual.
Strange Whining Sounds
You may also hear a loud, grating noise from the engine’s front end.
It is usually an indication of low-power steering fluid. However, since the water/air mixture has made the fluid thicker than usual, this can also lead to a whining sound.
The thicker fluid is harder to move around by your power steering pump.
How to fix a milky power steering fluid
Let’s finish by talking about how to fix milky power-steering fluid.
What I would recommend
Check for leaks in all hoses
Check all hoses connected to the steering for leaks. Replace the hose if you discover a leak.
Drain all the milky fluid:
You can drain your power steering fluid now that you have identified the leaking hose.
To remove all fluid from the power steering system, disconnect the hose connected to the reservoir or use an oil pump.
Add Steering Fluid:
You will need to re-fill your power steering fluid after you have replaced the leaky hose/seals. Use the type recommended for your model and make.
Bleeding the power steering:
Before turning on the engine, bleed your power steering system. This ensures air bubbles have been removed from the system, preventing further leaks or issues.
To bleed air from the steering system, do the following:
Unlock the steering wheel by raising the front end of your car and turning the key.
You can also feel for fluid by tilting the steering wheel. Continue to turn the steering wheel to the left and right for 5 minutes.
Once you have completed all the steps, your vehicle is ready for driving!
