Or do I add coolant (50/50) untill comes out green out of the Tee?

Thanks again....
Once you are done flushing you can close off the tee adapter.

What I do after flushing is drain off as much water by opening the radiator drain plug. Since there will be water in the system you will not be able to calculate the proper 50/50 mix and only be able to guesstimate. The way around this is to premix to 50/50 using another clean container/bottle. I would not poor in pure coolant and attempt to figure it out. Also, use distilled water not tap water when you premix. I recall not using over 8 quarts or so of premixed coolant after a flush.

Sometimes it is better to buy ready to go 50/50 premixed coolant so you do not have to worry about the hassles of mixing.

After water is drained close drain plug. Poor in 50/50 coolant into the radiator filler neck until the level comes up. Then start engine with radiator cap off and let warm up until the thermostat opens, then top off radiator until full. Re-install radiator cap. Then make sure the coolant reservoir has sufficient coolant level. The last step is to make sure there is no air in the system by doing the bleed procedure.

Just to double check the coolant protection and mix you can get one of those cheapy cooling system testers. You can always drain a little coolant out later and then add pure coolant to get it to around 50/50.
