Take off the clip or the 10mm nut which ever one applies. Then the filter can be grabbed with a set of needle nose pliers. Crawl under the car where the PS sector is and locate the 12mm bolt in the back side. Take off this bolt and turn the wheel to the left lock (with the engine off). Then allow the fluid to drain . Reinstall the bolt and fill with fluid. Once you restart the engine, keep adding fluid to the right level.
