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.
