Test drive and cooling

So I got a good 80 mile round trip under her belt, this is at 80* in the morning-  yesterday's  100* 25 mile afternoon picture melted.
Notice no charging light glowing at you...

Everything's working good, noticed the temp gauge hovering high while driving, then in stop and go idling it headed towards H!

Found that MG was not known for accurate temp gauges on the forums. Kind of a suggestion gauge....


Anyway I got back here and with my nifty new radiator,  drained it and flushed it then refilled 50/50 premix. Draining and refilling radiator is just over 1 gallon btw....

So i used some technology to assess the engine with a Bullard TIC.

Idling, 90* ambient with gauge reading just above N.
Note the looped heater core hose the upper part of the picture.
Radiator is receiving about 165* water and very bottom return is at 100 ish.

Heres the plug side while it was just warming up.
