Overview

Power steering systems rely on hydraulic fluid to transfer pressure, allowing you to turn the steering wheel with ease.
This is especially likely if you have a leak in your power steering system.
The bleed screw is typically located on the power steering pump or the reservoir.

Are you experiencing a strange clunking or groaning noise when you turn the steering wheel? Does your car feel sluggish and unresponsive, like it’s fighting you every turn? These could be signs of air bubbles in your power steering fluid. This isn’t a problem to ignore, as it can lead to serious damage to your power steering system. But don’t worry, learning how to get rid of bubbles in power steering fluid is easier than you think! This blog post will guide you through the process, helping you understand the causes, symptoms, and solutions for this common automotive issue.

Understanding the Problem: Why Bubbles in Power Steering Fluid?

Power steering systems rely on hydraulic fluid to transfer pressure, allowing you to turn the steering wheel with ease. This fluid is designed to be incompressible, meaning it shouldn’t contain air bubbles. But when air gets into the system, it disrupts the pressure transfer, leading to the issues mentioned above.

Here are some common culprits behind air bubbles in your power steering fluid:

Low Fluid Levels: If your power steering fluid level is low, air can be drawn into the system. This is especially likely if you have a leak in your power steering system.
Loose or Damaged Hoses: Worn or damaged hoses can allow air to enter the system.
Faulty Power Steering Pump: A failing power steering pump can draw air into the system.
Improper Fluid Replacement: If the power steering fluid is replaced incorrectly, air can be introduced.

Recognizing the Signs: Symptoms of Air in Your Power Steering System

Before you start troubleshooting, it’s important to be sure you’re dealing with air in your power steering fluid. Here are some common symptoms:

Steering Wheel Feels Heavy: This is the most obvious sign. The steering wheel will feel harder to turn, especially at low speeds.
Clunking or Groaning Noise: You may hear a clunking or groaning noise when you turn the steering wheel, especially at low speeds.
Steering Wheel Shakes: In some cases, the steering wheel may shake or vibrate when you turn it.
Power Steering Fluid Level Drops: If you have a leak, you’ll notice the power steering fluid level dropping.
Fluid Appears Foamy: If you check the power steering fluid reservoir, you may notice that it looks foamy or bubbly.

How to Get Rid of Bubbles in Power Steering Fluid: A Step-by-Step Guide

Now that you know what to look for, let’s tackle the problem. Here’s how to get rid of air bubbles in your power steering fluid:

1. Park on a Level Surface: Ensure your car is parked on a level surface with the engine off. This will allow for proper fluid circulation.

2. Check Fluid Level: Open the power steering fluid reservoir and check the fluid level. If it’s low, add the correct type of power steering fluid. Consult your owner’s manual for the recommended fluid.

3. Bleed the System: This is the most important step to remove air bubbles. Here’s how to do it:

Locate the Bleed Screw: The bleed screw is typically located on the power steering pump or the reservoir. It’s usually a small, hexagonal-shaped screw.
Open the Bleed Screw: Use a wrench to loosen the bleed screw.
Turn the Steering Wheel: While the bleed screw is open, turn the steering wheel from lock to lock several times. This will help to force the air bubbles out of the system.
Close the Bleed Screw: Once the fluid runs clear and you no longer see bubbles, tighten the bleed screw.

4. Top Off Fluid Level: After bleeding the system, check the fluid level again and add more fluid if necessary.

5. Test Drive: Take your car for a test drive to see if the problem is resolved. If you still notice air bubbles, you may need to repeat the bleeding process or consult a mechanic.

Preventing Air Bubbles in the Future: Maintaining Your Power Steering System

Getting rid of air bubbles is a temporary fix. To prevent them from recurring, follow these tips:

Regular Fluid Checks: Check your power steering fluid level regularly.
Replace Fluid as Needed: Follow the manufacturer’s recommendations for replacing the fluid.
Inspect Hoses: Inspect the power steering hoses for leaks, cracks, or wear.
Address Leaks Promptly: If you notice a leak, address it immediately to prevent further damage.
Avoid Overfilling: Don’t overfill the power steering fluid reservoir.

Beyond Bubbles: When to Seek Professional Help

While the steps outlined above are effective for most cases, some issues require professional attention:

Major Leaks: If you have a major leak in your power steering system, you’ll need to have it repaired by a mechanic.
Damaged Pump: If your power steering pump is damaged, it will need to be replaced.
Complex Issues: If you’re experiencing recurring air bubbles or other complex power steering problems, it’s best to consult a mechanic for diagnosis and repair.

Steering Clear of Trouble: A Final Thought

Air bubbles in your power steering fluid can be a nuisance, but they’re usually easy to fix with a little effort. By following the steps outlined above, you can get rid of air bubbles and restore your steering system to its proper function. Remember to maintain your power steering system regularly to prevent future problems.
