230F coolant ain't dangerous in itself.
It's 20 degrees on the right side of boiling point with a 15psi cap.

You'd best check, or have your car checked to see if you've got a leaky gasket though.

im waiting for it cool off - it seems the oil level is unchanged and there is no white smoke out the back......is it possible I just let the coolant reservoir get way too low? there is a LITTLE bubbling in the reservoir like very slow bubbling......i checked dipstick 8x to smell it etc......car has been running 100% until today ...also the reservoir warning never got triggered for some reason

im dreading its head gasket...only has 145k on it so i was hoping nothing major for a while....\

once i refilled the reservoir it stayed rock solid between 200 and 210 the whole drive home

edit: going to buy compression tester and head gasket fluid tester for radiator...thank god i have a spare jeep

I had my neighbor take a look at it and I'm starting to think I have a leaking heater core......I assumed the dripping on the passenger dashboard side was from the AC condensation but it drips even when the AC is off...that would explain the loss of fluid and that drain cock is definitely wet the one below the 2 heater core inlet hoses

edit: is it possible for a heater core to leak that much without any window fogging? assuming ~90 degree outside ambient temps?

once i throw a valve on the heater core inlet hose it will stop leaking as soon as the fluid level gets down to the level of wherever on the heater core the leak is right? assuming I don't need heat any time soon i should be fine to delay the heater core change for a few months?

edit2: after sampling a good deal of fluid from the drain cock on the firewall side it is slightly sticky which makes me think this is like a 4:1 water:coolant mixture because its mixing with the AC drain condensation but it IS too sticky to be just AC drain
