Today I did a PS flush and a coolant flush on my 92 400E! Both were simple, for the PS flush I did the suck out fill start the car turn the wheel, then do it again and again and again until its clean! I did not want to mess with the lower PS hose since I got it to stop leaking a month ago! coolant flush was easier then an oil change!!! Twist the little red cap on the bottom of the radiator open the rez tank close it back up and refill super easy unlike my 05 minicooper s PITA!!! I also did the rear diff fluid last weekend that stuff was NASTY!!! coolant and PS were not that bad though! Check those off the list!!! Tommorrow Oil and filter and maybe Y-pipe and Magnaflow Exhaust !!!!!!
