Symptoms Of A Bad Power Steering Pump

A properly functioning power steering pump is essential for the smooth operation of the vehicle’s steering system. When this component begins to fail, it can significantly affect the driving experience and even compromise safety. Recognizing the symptoms of a bad power steering pump early can help you address issues before they escalate into more severe problems. Here’s a detailed guide on the symptoms to watch for.

Replacing Power Steering Pump: Quick DIY Guide


1. Whining Noise When Turning the Wheel

One of the most common signs of a failing power steering pump is a groaning or whining noise when you turn steering wheel. This noise is usually most noticeable at low speeds or when maneuvering into a parking space. It can indicate that the pump is struggling to circulate fluid properly, often due to low fluid levels or internal wear and tear.

2. Stiff or Unresponsive Steering

If you notice that the steering wheel becomes stiff or unresponsive, it could be a sign that the power steering pump is failing. The pump provides the necessary pressure to help you turn the wheel effortlessly. When it starts to fail, you may experience increased resistance, making it difficult to steer, especially at low speeds or when stopped.

3. Squealing Noises

A squealing noise when you start the car or make sharp turns can also point to a problem with the power steering pump. This noise is often caused by a loose or worn-out belt that drives the pump. If the belt slips or doesn’t have the right tension, it can create a squealing sound, indicating that the pump isn’t operating efficiently.

4. Fluid Leaks

Power steering fluid leaks are a clear indicator that something is wrong with the system. If you notice puddles or spots of red or pink fluid under your vehicle, it’s likely that your power steering pump or one of the associated hoses has a leak. Leaks can lead to low fluid levels, which in turn can cause the pump to fail.

5. Foamy or Discolored Power Steering Fluid

Regularly checking your power steering fluid can help you catch issues early. If the fluid appears foamy, bubbly, or discolored, it might be contaminated or aerated. This condition can result from air entering the system, which often happens when there’s a leak or when the fluid levels are too low. Contaminated fluid can’t lubricate the pump effectively, leading to further damage.

6. Vehicle Stalls or Engine Performance Issues

In some cases, a failing power steering pump can put extra load on the engine, causing it to stall or exhibit performance issues. This symptom is less common but can happen if the pump seizes or creates excessive drag on the engine. If you notice the vehicle stalling or experiencing unusual performance problems, it’s worth checking the power steering pump as a potential culprit.

7. Burning Smell

A burning smell coming from the engine bay can indicate that the power steering pump is overheating. This might happen if the pump is working too hard due to low fluid levels or internal damage. Overheating can cause the fluid to break down, reducing its ability to lubricate and protect the pump, which can lead to failure.

Step-by-Step Guide to Replacing Power Steering Pump

Follow the steps below to replacing the pump properly –

Step 1: Prepare the Vehicle

  1. Park Safely: Ensure the vehicle is parked on a flat, level surface. Engage the parking brake for added safety.
  2. Disconnect the Battery: To avoid any electrical issues, disconnect the negative battery terminal.

Step 2: Drain the Power Steering Fluid

  1. Locate the Power Steering Pump: It’s usually found on the front of the engine and is driven by a belt.
  2. Place a Drain Pan: Position a drain pan underneath the power steering pump to catch the old fluid.
  3. Disconnect the Hoses: Using pliers, disconnect the high-pressure and return hoses from the pump. Allow the fluid to drain completely.

Step 3: Remove the Old Power Steering Pump

  1. Loosen the Belt: Loosen the tensioner pulley to remove the belt from the power steering pump pulley.
  2. Remove the Pulley: Use a pulley puller tool to remove the pulley from the pump shaft. This tool ensures you don’t damage the pulley.
  3. Unbolt the Pump: Use a socket set to remove the bolts securing the pump to the engine. Carefully lift the pump out of the engine bay.

Step 4: Install the New Power Steering Pump

  1. Transfer the Pulley: Attach the pulley to the new power steering pump using the pulley puller tool. Make sure it’s securely in place.
  2. Mount the New Pump: Position the new pump in place and secure it with the bolts. Tighten them to the manufacturer’s specifications.
  3. Reconnect the Hoses: Attach the high-pressure and return hoses to the new pump. Ensure they’re securely connected to prevent leaks.

Step 5: Reinstall the Belt and Refill Fluid

  1. Reinstall the Belt: Loop the belt over the new power steering pump pulley and adjust the tensioner pulley to ensure proper belt tension.
  2. Refill Power Steering Fluid: Open the power steering fluid reservoir and fill it with the recommended fluid. Check the vehicle’s manual for the correct type.

Step 6: Bleed the Power Steering System

  1. Jack Up the Front End: Raise the front of the vehicle with a jack and support it on jack stands. This allows the wheels to turn freely.
  2. Turn the Steering Wheel: With the engine off, turn the steering wheel from lock to lock several times to expel air from the system.
  3. Check the Fluid Level: Refill the reservoir as needed during the bleeding process to ensure it doesn’t run dry.

Step 7: Test the New Pump

  1. Lower the Vehicle: Remove the jack stands and lower the vehicle back to the ground.
  2. Reconnect the Battery: Reconnect the negative battery terminal.
  3. Start the Engine: Start the engine and turn the steering wheel from lock to lock to check for smooth operation. Listen for any unusual noises and check for leaks.
