no. if it looks clean in the reservoir you are good. that coolant looks brown, but it's probably mixed with dirt and the low lighting.

 

I would simply not touch that bleed screw.
Bleed it like a discovery I.
Put the coolant bottle up high by unhooking it.
Run the engine at a fast idle with the coolant tank cap off.
Bubbles all come out in about 10 minutes and you did not have to
risk damaging that bleed screw.
But, Mike has great advice.
Replace all that stuff.
Bleed screw and the T fitting.

 

Hate to correct someone but that is 100%, the wrong way to bleend a D2.
Only bleed it with a stone cold engine, with the engine "OFF", remove the bleed screw, fill thru the coolant bottle till you get a steady stream thru the bleed screw, then replace the screw and the cap.
After driving it, and before your first cold start, top it off one more time to with in an inch of the cap, recheck the level a few days later also before a cold start as that is the best and most accurate time to check the level.

 

Hi Mike, happy Labor Day : )

You're absolutely right only bleed it when engine is stone cold. I removed bleed screw when engine is hot and now I have a broken bleed screw and all shops and dealers are closed on holiday. So I went to Home Depot buy a 1/8-NPT plug replace my cracked bleed screw.

What is the correct thread size on factory original bleed screw?

 

I still run the original hose just because i have not had someone able to help me change it yet. The updated hoses are in the truck waiting. Not recommended they should be changed asap like Mike said.

 

X3 only bleed stone cold
