You can pull of the return hose stick it in a bucket and while someone turns the wheel lock to lock add fluid to the resivoir the cooler i think you are refering to is the power steering cooler

^^^^ this is what I did. I put in synthetic ATF. Seems much quieter.

I pulled that hose and did just that. Got myself a huge funnel and mobil1 synthetic fluid and went to town. I put 4 quarts through it, now the little vent hole in the ps cap lets out the smell of tranny fluid, smells like poo but its ok. I like knowing that the fluid is new.

turn the wheel lock to lock and add fluid? Is the motor running or off?
i would of thought that running with the cap off would shoot fluid out?

Don't need pics, just follow the return hose from the brake booster and pull it and place in a bucket as already said. Yes the motor has to be running, how else does the pump , pump the old fluid out. 3 quarts should be enough, you will see the change in fluid color, and smell, lol!!! Synthetic ATF makes a big difference at idle and in the cold winter months.

NCH - ATF is ok in there? no need for power steering fluid?

I was reading about this on the benz forum and they also suggest ATF
