Replacing Power Steering Fluid and Power Steering Filter
by Herbert Rocha
First and foremost, I would recommend getting a pair of safety glasses. As you read along in this description, you will know why.
Items that you will need are the following
Put on your safety glasses.
Clean the area around the power steering cover and remove the cover. Remove it slowly because there may be tension on the power steering cover if the spring located inside has lost the retaining clip or lost the ability to retain tension on the spring. See note below.
Place a small coffee can adjacent to the power steering pump; away from the pulleys and in a stable area. I chose the area right behind the driver side headlight.
Identify the return rubber hose at the power steering pump; the return hose is the hose without the pressed fitting and just has a regular screw clamp.
Disconnect the return hose at the power steering pump by unscrewing the clamp and pull the hose away from the steel fitting; you may need to twist the hose back and forth for it to come out but it will.
Place the hose into the small container.
To drain the oil, have your assistant start the car. Once the car has started, the power steering pump will drain all the oil from the reservoir. Once you see that no more oil is draining into your small container and no longer have a steady stream, have your assistant stop the engine.
Note: At this time you be able to see into the reservoir. You will see the center shaft, and a spring surrounding the shaft held down with tension by a small clip at the top of the spring. At the very bottom of the reservoir, you will see a round plate. Underneath this plate is the location of the power steering filter.
Carefully, using your needle nose pliers, remove the spring clip. Be careful not to lose the clip because it can fly off into the air if disturbed and get lost or hit you in the eye (reason for safety glasses). Remember that the spring clip is under tension because of the spring that is directly underneath it.
Remove the spring.
Remove the round plate.
Remove the power steering filter.
Reconnect power steering hose
Replenish the reservoir with new fluid at the mark indicated on the inside of the reservoir.
Have your assistant start the car again. Do this long enough so you no longer have a steady stream of oil coming out of the rubber hose. This process will flush out the reservoir and the power steering box.
Continue this process a few times of replenishing, starting the engine and draining until you are satisfied that the oil is clean. You will notice the change in color of dirty oil compared to clean oil.
With the reservoir empty, place the new power steering filter into position, along with the round plate, the spring and the metal clip. Provide enough tension on the spring with the clip to hold the filter assembly in place and enough to space clear the cover when the cover is put back on.
Fill the reservoir with fluid at the maximum indicated on the inside of the reservoir, and start the car. The fluid should go down slightly because it is filling the power steering box and the return hose.
Stop the engine. Add enough fluid to the recommended level if needed.
Place the cover back on the reservoir and tighten with the lock nut. You are done.
