How To Flush Power Steering Fluid?

Draining and replacing power steering fluid takes a long time. Therefore, you should consider the appropriate maintenance time so as not to affect daily operations. To drain the liquid, you need to do 3 steps:

Step 1: Check power steering fluid level

This is an important step you need to perform correctly because it affects the quality of the new fluid after replacement. You need to check the condition of the power steering fluid and locate the reservoir, remove the cap and pour it in.

If the liquid is dark or dirty, wipe a small amount of the liquid on a paper towel.

Then you observe the liquid layer on the towel to determine their quality. From there, you will consider moving on to step 2 or not. Normally, you will need to perform step 2 because most of your vehicles will be contaminated and not quality after a period of use.

Step 2: Clean the liquid tank

To clean the liquid tank, you can use water. Because water and oil do not dissolve, you can use this method. 

At the same time, if you only vacuum the container without using water to clean it, it will affect the quality of the new liquid. Because most likely, the tank will have sediment and old liquid still in the pump and lines. 

Therefore, you need to refill and wash the tank several times to ensure the liquid chamber is clean, free of impurities or dirt.

Step 3: Proceed to drain the new power steering fluid inside

After cleaning the tank, you can move on to step 3 to drain the new power steering fluid inside. 

  • First, you need to locate the low-pressure line in the power steering system. Typically, this line will run from the transmission or steering rack to the fluid reservoir.
  • Next, you need to disconnect the low-pressure lines and put them in the oil drain pan. If this line is hard, you should consider using a spanner to avoid damaging the nut.
  • You will then start your car’s engine and allow the power steering pump to pull the fluid out of the reservoir. At the same time, the pump will push the old liquid out of the low-pressure line.

It would help if you ensured that the tank always has liquid inside to prevent air from drawing inside the system. Therefore, when starting the car, you need to pay attention to the drain tray while keeping the tank full.

Finally, after the new fluid inside the low-pressure line is about to run out, turn off the engine and reconnect the cable.
