How To Flush Your Car’s Power Steering Fluid?

Almost all modern cars today are equipped with hydraulic power steering. This system should always be kept lubricated. For this, you should always use a lubricating oil containing a mixture of base material and other additives so that it works efficiently without any problems. The power steering is supposed to have a useful lifespan equal to the life of the car. But for this, your system should not show liquid leaks during the operation. The use of deficient oil or its premature replacement are the most frequent reasons why power steering breaks. In another case, if your vehicle suffers a serious mechanical problem in the steering pump, it is possible that you have to drain your liquid oil direction.

How To Flush Your Car’s Power Steering Fluid?

Here we explain step by step how to change or replace the power steering fluid easily without having to take your car to a mechanical workshop:

  1. Park the vehicle in a flat place and turn off the engine.
  2. Open the bonnet and secure it with the rod.
  3. Remove the filter located at the top of the power steering system (For the exact location, check the owner’s manual of your vehicle).
  4. Separate the overflow tank from the radiator, this makes it easier to get to the power steering reservoir. Keep the deposit handy since you will put it back soon.
  5. Disconnect the hose from the tank that should be located at the bottom. Sometimes this hose is difficult to remove therefore you must have a little patience.
  6. Replace the reservoir hose with another hose that should lead to an empty container. That container will be used to store the old liquid as it leaves the power steering reservoir.
  7. Grab the hydraulic jack and lift the front of your vehicle.
  8. Then add the new liquid to the deposit of the power steering. As you add the new liquid, it will force the old liquid into the tube, that you have connected, to move at the bottom of the tank to exit.
  9. Then enter your vehicle and move the steering wheel from one side to the other. The wheels should be locked in place but allow a small range of mobility. This will help the additional liquid remaining in the power steering system to finish draining.
  10. Verify that the container you placed is filled with the old liquid. This will ensure that the new liquid is in the power steering system.
  11. Disconnect the hose from the container and then replace the original tank hose.
  12. Check if more liquid is needed in the power steering reservoir and pour a little more until it is full.
  13. Move the steering wheel from one side to another a couple of times so that the new liquid penetrates throughout the system and does not leave air trapped inside it.
  14. Finally, put the filter of the power-assisted steering tank back in place and close the hood.
