Perfect for flushing the power steering fluid on my 2008 Expedition. Using a turkey syringe, removed most of the old liquid from the reservoir, removed the bottom hose and placed in a used Gatoraid bottle to catch the liquid that was about to leak. To plug the socket, I attached a balloon with a rubber band. I filled the tank very slowly, trying to keep the old one down. Lift the front of the car and turn the steering wheel from side to side to squeeze out all the old liquid. Don't start the car or you'll run dry in seconds and have a huge mess to clean up. Keep filling the reservoir as you don't want it to run dry and suck air into the system. When the liquid turns a nice shade of red, you're done. I used about half of this tank for washing and refueling. Save the rest for the next flush in 30,000 or to remove and replace exactly what's in the tank from time to time.
