Celebrations cut short.  Violins start to play...

Is it possible I have a bad Tstat?
-any opinions and suggestions are MOST welcome...

after more extensive driving around, engine temp is controlled well above
what I am used to (IE (bottom 1/3 of the LED)...
-temperature gauge:  centreline of the needle is about 1 full LED
diameter above the centre of the LED
-temperature scanner reads 225F on the return pipe to the water pump

At idle, the coolant fan comes on and controls the temperature at this
elevated temperature.

Radiator and upper TSTAT vent are well purged of air.

LED never comes back on after engine start.

Part Numbers:
Tstat: 025-121-113F ("Mahle Suitable for VS TX 24 87D")
Temp switch: 030-43-1016
Temp sensor: 025 906 041 A
