How To Bleed Power Steering Systems

Power steering is a crucial component of any vehicle, allowing for easier and more precise steering control. However, at times, air can enter the power steering system, causing issues such as difficulty in turning the steering wheel and potential damage to the system. In such cases, it becomes essential to bleed the power steering system to remove the air and restore proper functioning. In this article, we will discuss step-by-step instructions on how to bleed a power steering system and ensure your vehicle’s smooth and safe operation.

How To Bleed Power Steering Step By Step

How To Bleed Power Steering Step By Step

Power steering is a crucial system in modern vehicles that makes steering easier and more manageable for the driver. It utilizes hydraulic pressure to assist in turning the wheels, making it easier to steer especially at low speeds. Over time, air can get into the power steering system, causing it to function improperly and reducing the overall performance of the vehicle. This is where bleeding the power steering system becomes necessary. Bleeding the power steering system is the process of removing any trapped air from the system, restoring it to proper functioning. Below are the steps to help you properly bleed your power steering system.

Step 1: Gather necessary tools and materials
To bleed your power steering, you will need the following tools and materials:
– A clean container to collect old fluid
– A new bottle of power steering fluid
– A turkey baster or a small syringe
– A rag or paper towels
– A pair of safety goggles

Step 2: Locate the power steering reservoir
Before starting the bleeding process, locate the power steering reservoir. It is usually situated on the engine and is marked with a steering wheel symbol. Ensure the reservoir is at the correct level by checking the dipstick or by inspecting the markings on the side of the reservoir.

Step 3: Raise the front of the car
To facilitate better access to the power steering components, lift the front of the car using a jack and secure it with jack stands. This will also help to release any air bubbles trapped in the system.

Step 4: Turn off the engine and remove the reservoir cap
Ensure the engine is off, and the car is in park or first gear. Locate the cap of the power steering reservoir and remove it.

Step 5: Fill the reservoir with fluid
Using the turkey baster or a small syringe, remove as much of the old fluid from the reservoir as possible. This will help in removing any contaminants that may have accumulated in the reservoir. Next, fill the reservoir with fresh power steering fluid to the recommended level.

Step 6: Turn the steering wheel
With the engine still off, turn the steering wheel from lock to lock (from one extreme end to the other) a few times. This will help to push out any remaining air bubbles in the system.

Step 7: Check the fluid level
After turning the steering wheel, check the fluid level in the reservoir. If the level has dropped, add more fluid to maintain the recommended level.

Step 8: Start the engine and repeat
Start the engine and repeat the turning of the steering wheel from lock to lock. This will help to circulate the fluid and allow any remaining air to escape. Keep checking the fluid level and add more fluid as needed.

Step 9: Clean up
Once the fluid level stabilized, turn off the engine and clean any spilled fluid using a rag or paper towels. Make sure the reservoir cap is securely back in place.

Step 10: Test drive
Take your car for a short drive to ensure that the power steering system is working correctly and the steering feels smooth and responsive.

In conclusion, bleeding the power steering system is a simple process that can greatly improve the performance of your steering. It is recommended to bleed the system every time you replace the power steering fluid or when you notice any changes in your steering. By following these steps, you can easily and effectively bleed your power steering system and keep your vehicle running smoothly.


In conclusion, knowing how to bleed a power steering system is an essential skill for any car owner or mechanic. It not only ensures the proper functioning of the power steering system but also promotes the overall safety and performance of the vehicle. As highlighted in this article, the process may seem intimidating at first, but with the right tools and techniques, it can be easily accomplished. Remember to always consult the car’s manual and follow the correct procedure to avoid any mishaps. Regularly bleeding the power steering system will also prolong the lifespan of the system and prevent any potential issues. So, take the time to properly bleed your power steering system and enjoy a smooth and efficient driving experience.
