2009 GT500. Did a search and found an older post on milky pink power steering fluid (ATF) in the reservoir. I would assume it has been contaminated by water. It has a Shelby cap which does not fit snug so maybe condensation has accumulated. If not, what should I look for?
What is the capacity of the system and is there any particular ATF that you would recommend?
Thanks

Your problem is that the Shelby cap is vented on top and also acts as a bowl. water comes thru the hood vents, sits in the cap and drains into the reservoir. This also causes it to blow oil out going thru the hood vent and onto the windshield. Simply draining the reservoir and refilling does not work. All components and lines must be removed and cleaned. If you choose to keep the Shelby cap I’ve found placing a sandwich bag over the cap when washing the car eliminates the issue, if driving in rain, install your factory cap, unfortunately this is a slight flaw in the Shelby cap.

Thanks for your reply. I never noticed the vent hole on top. I think I will add a right angled vent to the top.

Decided on a simple straight vent pipe. Flushed the system out again and we’ll see what happens. Filled with Mobil 1 ATF.
