My bad, the rings are at the ends, but yes those are sweating out quite a bit. Not a drip, but like heavy sweat.
While sitting there with the car running doing that, the upper radiator hose, at the radiator, busted open and sprayed all my coolant on the ground.
no the hose was not ruptured, it seemingly burst a seam somewhere.
radiator is cracked
With all of these data, the coolant spray that you saw was from the crack radiator neck, not from the busted open hose. Engine was overheating while idling in hot weather with the electric fan not running properly. The coolant pressure was up so high that it caused the radiator neck cracked. I would be worried about the head and gasket. Keep an eye on the coolant level to see if it drops.the rings are at the ends, but yes those are sweating out quite a bit.

Well I have good news and bad news after doing all the work.A Nissens radiator is a quality OE replacment option if you do not want to go with genuine BMW.

Once you know there are no headgasket issues, it would be strongly advised to replace the rest of the cooling system, unless you know for certain it has been serviced recently with quality parts. In particular the expansion tank but also tstat, water pump and radiator hoses should be replace with either genuine bmw or quality OE.
I think that fan has been pointed out several times and probably had nothing to do with the other busted parts. In fact this was your most likely root cause.Well I have good news and bad news after doing all the work.
Good news is there is no coolant leak or headgasket damage (seemingly)
Bad news is now the elec. aux fan still will not spin up. Hesitant to try getting the engine even CLOSE to the midpoint without it :\
Too early to tell about the head/gasket. Keep checking the coolant level in the cold morning and if the level not drop then you should be very happen. It it dropped, then either external leak or leaked into the combustion and much headache.Good news is there is no coolant leak or headgasket damage (seemingly)
Try to run engine with the lower hose sensor connector removed, as this should cause the fan to run at max speed.Bad news is now the elec. aux fan still will not spin up.
Man, we are not mind readers. What connector?I put the connector on backwards
located at the upper right corner of the radiator? If yes, it is impossible to connect this connector reverse 180 deg around.the fan connector plug with 3 wires.
