Pumping the working fluid of the power steering is the process of circulation of this fluid in the power steering system of a car in order to ensure the correct operation of this system. This procedure is not difficult, and you can perform it yourself even without special knowledge and with minimal experience in the field of mechanics. Here are a few steps to help you learn how to pump power steering fluid.

Steps

1. 1 Raise the vehicle with a jack, while ensuring that the front wheels are raised sufficiently to allow you to easily reach the underside of the vehicle.
   • Since you will be turning the steering wheel, a jack stand is recommended that does not restrict wheel rotation.
2. 2 Locate and remove the fluid collection pan that is located under the power steering system.
3. 3 Drain the power steering fluid by disconnecting the low-pressure hose from the steering pump at its lowest point.
4. 4 Reconnect the hose.
5. 5 Unscrew the power steering fluid reservoir cap and add the manufacturer's recommended amount of fluid.
6. 6 Replace the lid to close the reservoir.
7. 7 Start the engine and turn the steering wheel from one extreme position to the other within 5 minutes.
8. 8 Listen for a humming sound, which indicates that air has entered the system.
9. 9 Continue turning the steering wheel until fluid is properly circulating through the system and any remaining air is expelled from it.
10. 10 Stop the engine and let it sit for a few minutes.
11. 11 Disconnect the low-pressure hose again and allow the fluid to drain completely.
12. 12 Connect the hose and fill the reservoir with the correct amount of fluid.
13. 13 Start the engine and start turning the steering wheel to get rid of any air that has entered the system.
14. 14 Stop the engine again and let it stand.
15. 15 Repeat the filling, steering and draining process as many times as necessary until you have pumped 2 liters of fluid through the system.
16. 16 Lower the vehicle and start the engine again.
17. 17 Make sure the steering wheel works properly when the weight of the vehicle is loading the wheels.

Tips

• When cleaning the air, it is very important not to overflow the liquid in the tank. It is ideal to fill the liquid to the midpoint between the minimum and maximum.
• Since cars differ by year of manufacture, manufacturer and make, it is always recommended to read the owner's manual for specific details of any maintenance procedure.
• For safety reasons, make sure you are wearing suitable clothing and safety goggles before starting work.
• Pumping the power steering fluid typically requires six separate cycles.
• Performing a pre-scheduled pumping of the power steering fluid is an essential part of keeping your vehicle running.
• Always dispose of drained fluid responsibly and with concern for the environment.
• If, after pumping 2 liters of fluid through the system, you still hear a buzzing noise when the steering wheel is turned, then in order to displace the air, you will need to remove the fluid reservoir.
