Well, I never saw a bleeder...but I didn't look real hard either. What I did do was to siphon the reservoir dry, including the tube going to the steering box, and refilled it with new juice (I'd removed the filter for this). Fired the car up, let it run for a minute, then went thru the process again maybe 6-7 times. Used up 2 quarts of fluid, and think the job called for closer to 3 since the fluid still has a slight red tinge to it (replacement fluid's yellow). Big improvement, though-now you can read the writing on the filter through the fluid.
I'm gonna pick up a bunch of fluid and do all the cars-it looks like this system works pretty hard.
