So... My power steerting pump is whining at me when it is cold and I turn the wheel. So I thought I better check the fluid. Found out it is not even touching the dip stick, I know total chick move. Either way, I just want to mnake sure that I am putting things where they need to go. The reservior behind the radiator is the one that I need to fill correct? The fluid that is in there currently is red which is obviously transmission fluid. Is that where I need to put more fluid into? Do X5's use the same fluid for both transmission and PS? Finally, is there any approved fluids that have a stop leak in it, or are those bad news? Thanks as always!
