What Color Is Power Steering Fluid Supposed To Be?

Power steering fluid is what makes your steering run smoothly and lets you drive the car. But what color is power steering fluid supposed to be? What color should I be worried about, and what color indicates that all is fine? Let’s find out!

Cars are heavy. Your average car might weigh about 4000 pounds. Imagine trying to steer a 4000-pound beast with your bare hands! It’s impossible to steer a modern-day car with a purely manual system. That’s why cars today have hydraulic power steering systems.

The power steering fluid plays the primary role in the hydraulic power steering system. It creates a hydraulic link between your steering wheel and the front wheels of your car. 

This reduces the effort required to turn the steering wheels. Moreover, the fluid even helps lubricate the moving parts of the hydraulic power steering system.

You will find power steering fluid in a reservoir under the hood, usually on the car’s driver’s side. The reservoir is white with a black cap and has steering fluid written on top. 

When you open the power steering fluid reservoir, the first thing you should notice is the color of the fluid. What color is the power steering fluid supposed to be? Power steering fluid is supposed to be either pink or red. But if it is dark brown or foamy, it needs to be changed. I will discuss more about power steering fluid, what it’s used for and what its color signifies. Keep reading for more information.

What Is Power Steering Fluid?

The hydraulic power steering system consists of major components like a vane pump, rotary vane, power steering fluid reservoir, and hydraulic chamber.

The vane pump is usually connected to the engine of your car. Whenever you start steering your vehicle vane pump starts drawing power from the engine and pumps the power steering fluid to the rotary vane, finally making its way to the hydraulic chamber. 

In the hydraulic chamber, a piston separates the hydraulic chamber into two equal portions, i.e., the left and right sides. The power steering fluid is redirected in both chambers but not equal amounts. 

It means in one chamber; you will find more power steering fluid compared to another chamber which creates a pressure difference in the hydraulic chamber. 

The power steering fluid always pushes the piston towards the weak side of the hydraulic chamber, and the steering rack moves accordingly.

If the steering rack moves to the right, your car wheels will also move to the right side. Now power steering fluid will go back to the reservoir to repeat the process.

What Are The Types Of Power Steering Fluid?

#1. Mineral Power Steering Fluid

The mineral power steering fluid consists of petroleum fractions and few additives. It works wonders for rubber components, i.e., it lessens wear and tear and increases the life of all the components of the steering system. 

The mineral steering fluid is also less expensive than other power steering fluids. However, it has some disadvantages as it runs away very quickly and you need to replace it with a new one.

#2. Semisynthetic Power Steering Fluid

The semisynthetic fluid is a mix of both synthetic fluid and mineral fluid. It is a good lubricant compared to all other steering fluid types available on the market and works wonders for metal components but not for rubber ones.

A Few Final Words

The power steering fluid is usually a red, pink, or clear liquid. But if you find power steering fluid leakage as black or brown color, then it’s time to replace it as soon as possible.

There are different power steering fluids available in the market. But, you need to find the appropriate power steering fluid suitable for your vehicle.

Then use a jack to lift the front portion of your car and then open the hood. You will find a reservoir where the power steering fluid is generally stored. Open the cap off the reservoir, remove all the old liquid, and replace it with a new one.

Then remove the jack and get your car back to ground level. Allow the engine to run for a few seconds or go out for a short drive and then check the fluid level in the reservoir. If you are satisfied, then you have successfully replaced the power steering fluid.
