To bleed or not to bleed.....

Hey guys, this one's kind of a no brainer
but dammit, it's got me scratching my head like crazy...

Long story short: I bought my first e30 a little bit over a month ago.
1990 325i. 4 door. Stick. She's a beauty, but a work-in-progress.

So, this week, my power steering started screeching. A sound I know all to well.
Opened up the reservoir, lo and behold it was practically empty.

Not really sure wtf the last owner did, but what's left of the "power steering fluid" is this nasty, gunky, dark grey/black sludge...if you could even call it that.

From previous experiences, I've known ATF to be a nice shade of dark red.
Kinda like wine

Went down to the stearlership and got me some reverse-compatible Dexron iii.
Sure enough, it was dark red. Just the way I like it..

Just wondering what this mystery fluid could be. lol
Maybe Dexron ii? Or even old Dexron ii that got burnt up from being in there so long? Who knows....

Anyways, what is left of the burnt up mystery fluid covers up about 5-10% of the reservoir... Just barely enough to say there's anything in there at all...

Dare I be lazy, and just pour the new ATF in the reservoir?
Just kidding...i'm 99.999999999% sure i gotta bleed this mystery gunk out before pouring in the new ATF.

Any good, time saving, advise on how to do this? I feel like it should be pretty self explanatory,
but i'm still getting used to my M20

It looks like i can disconnect the small hose beneath the reservoir, let it bleed, then cut the wheel left and right a couple times to bleed out the rest of the gunk and air.

Am I right?

Also, I won't be lifting the car. It looks like i might have to remove the MAF and ICV for easier access to the hose.
Good idea, or bad?
