by

When air infiltrates your vehicle’s power steering system, it can gradually deteriorate its performance and capabilities. The outcome? A compromised power steering system that can make your driving experience a nightmare. However, you can prevent major issues caused by power steering failure if you can identify the symptoms associated with air in the power steering. In this article, we will explore the common signs that indicate the presence of air in power steering symptons and its associated troubles.

Recognizing the Signs of Air in Your Power Steering

If you find it uncomfortable or challenging to control your vehicle’s steering. This is the first hint that something might be amiss with your power steering system. Additionally, unusual whining, grunting, moaning, or growling noises and difficulty in maneuvering the steering wheel while driving are the most prevalent indicators of power steering issues.

4 Telltale Symptoms of Air in Your Power Steering

Beyond the obvious signs mentioned, there are other significant symptoms that can help you identify the presence of air in your vehicle’s power steering system.

1. Unusual Noises, Stiff or Hard Steering, and Bubbles in the Reservoir Fluid

When air infiltrates your power steering, you’ll likely hear unusual whining sounds, especially when turning your vehicle’s wheel. The steering wheel may become hard to turn on different gears. If you notice that your steering wheel has become stiff or hard, this is a clear indication of power steering damage due to trapped air. You might also observe bubbles in the reservoir fluid or that the fluid has become foamy and low. If you pay close attention, you’ll hear a moaning sound when turning the wheel left or right. These are clear signs that something is amiss with your power steering system, specifically the presence of air within the power steering pump or system.

2. Loss of Power and Slow Response

If your vehicle’s steering suddenly feels like manual steering, it’s essential to check your power steering for the presence of trapped air. The entry of air into your power steering can result in a loss of power. Even at low speeds, you might hear a growling noise. Another symptom is experiencing a slow response from your vehicle’s steering wheel while turning corners. These signs all point to power steering failure, indicating a potential need for replacement.

3. Loss of Steering Fluid or Steering Fluid Leak

The effectiveness of the power steering system relies on a consistent, high-level of steering fluid. If you notice a visible leak or realize that the fluid level is significantly low, it’s advisable to inspect and confirm whether excessive air has infiltrated the power steering, leading to failure and fluid loss. To check the fluid level, consult your user manual and follow the provided instructions.

4. Pulsation or Vibration in the Steering Wheel

When you encounter a vibrating or pulsating sensation emanating from your vehicle’s steering wheel during idling, this may signal a potential power steering failure. These sensations are most noticeable during particular turning points. Such pulsations and vibrations are common symptoms that warn you of a failing fusible link.

In conclusion, understanding these symptoms is vital to maintaining your vehicle’s power steering system. If you detect any of these signs, it’s advisable to address the issue promptly to prevent further damage and ensure a smoother driving experience.

What to Do After Detecting Air in Your Power Steering?

Once you’ve identified that your vehicle’s power steering is failing due to the presence of unwanted air, follow the steps below to address the issue:

Inspect Thoroughly to Confirm Air Existence in Power Steering

After experiencing any of the aforementioned signs or symptoms, begin by checking the power steering fluid level and topping it off. Observe your power steering’s condition. If topping off the fluid resolves the unusual sound, and your power steering returns to normal, you may have no cause for concern.

However, if the noise persists and your power steering remains problematic, there’s a high likelihood of a leak and trapped air in your power steering system.

Removing the Existing Power Steering Pump

  1. Start by disconnecting your vehicle’s battery cables and the power steering belt.
  2. Position a drain pan correctly before removing the current power steering fluid.
  3. Remove the power steering pressure and replace hoses from the old power steering pump, ensuring no other components are attached to the pump.
  4. Use the recommended tools specified in your vehicle’s user manual to eliminate all pulleys and bolts.
  5. Remove the old power steering pump.

Installing the New Power Steering Pump

  1. Place the new power steering pump into the bracket and secure it by tightening all the connecting bolts and connectors. Replace old bolts or connectors if necessary.
  2. Use a pulley press to install the power steering pump pulley, starting by screwing in the hub press within the bolt.
  3. Grease the pump hub and its pulley, then replace the pulley on the hub and align it.
  4. Reattach the belts, ensuring that the power steering pulley is aligned with the crankshaft pulley.
  5. Insert the air conditioning and Serpentine Belts, ensuring they are properly aligned and secured.

Flushing the Air Out

If you’ve had issues with leaking in your power steering system, you’ll need to replace the pressure hose or the power steering pump. Follow these steps to flush out unwanted air:

  1. Park your vehicle safely on level ground and wait until the engine cools off.
  2. Open the hood and check the steering fluid level in the reservoir. Add fluid if necessary to reach the Full Cold level, but make sure to follow your vehicle’s manufacturer’s recommendations for the type of steering fluid.
  3. Use a floor jack to lift the wheels off the ground and secure your vehicle with jack stands.
  4. Start the engine and slowly turn the steering wheel left to right and right to left at least ten times, avoiding hitting the stops or locks. This will help force air out of the system through the reservoir and prevent seal damage.
  5. It’s advisable to have an assistant monitor the steering fluid level while you flush the air out.
  6. Ensure the reservoir doesn’t run dry during this process, adding fluid as needed to maintain the flow.
  7. Repeat the engine starting and turning steps until the steering fluid level stabilizes. When the steering wheel feels normal, and there are no bubbles or noises, shut down the engine. Your task is complete.

Is Replacing the Power Steering Pump Typically Expensive?

The cost of replacing a power steering pump can vary. If you take your vehicle to a service shop, you can expect to pay approximately $400 to $700. However, if you choose to replace the power steering pump yourself, the cost will be lower, ranging from $150 to $250. Keep in mind that costs can vary based on labor charges and parts prices, which depend on your vehicle’s make and model.

How Often Should You Check or Service Your Vehicle’s Power Steering Pump?

The lifespan of a power steering pump can vary depending on your vehicle’s make, model, and driving conditions. However, you can generally expect a new power steering pump to last for around 100,000 miles of operation.

In conclusion, while air in your power steering system won’t prevent you from driving your vehicle, it can certainly make your driving experience unpleasant and strenuous. It’s crucial to be aware of the signs and symptoms that indicate when air has infiltrated your power steering and take prompt action to rectify the issue.

Final Thoughts

In conclusion, understanding the air in power steering symptoms is crucial for maintaining a smooth and safe driving experience. While air in the power steering system may not render your vehicle undrivable, it can significantly impact your ability to steer, control, and enjoy your time on the road.

By recognizing the warning signs and taking prompt action, you can avoid further damage to your power steering system and ensure that your vehicle remains in optimal working condition. Additionally, addressing these issues promptly can prevent costly repairs down the road.

Regularly checking and servicing your power steering system is essential for keeping it in top shape and extending its lifespan. While the longevity of a power steering pump can vary based on your vehicle’s make, model, and driving conditions, a new pump typically lasts around 100,000 miles. To ensure the longevity of your power steering system, be attentive to any changes in its performance and address issues as they arise.
