I think thermal model Works fine during level flight and dogfights but low speed flight and taxi need some research. I have no data to prove any of my thoughts . I have just read from different sources that pilots were struggling to take off before overheating engine.

This is what i found with quick search
Me 109 G:
"The Messerschmitt was equipped with radiators in the wings. The air intake was a large opening near the fuselage, and the outlet was adjustable. The automatics adjusted the system according to the temperature of the glycol coolant.
- Was it possible to adjust the radiators manually?
Of course you could shut the flaps, the effect on speed was minimal. (Showing the position of air intake and outlet in the wing in relation to the fuselage.) If you took a hit there, the glycol would leak out. But you could shut off (the damaged radiator).
- Were the Finnish planes equipped with the shut off valves?
All our planes had these valves
- Was it so that the radiator flaps had to be open at takeoff, the engine would overheat easily?
Yes, it was absolutely necessary to take off as soon as possible to avoid overheating. "

MAP Temps play a big part.
You have to remember that all the maps are like -25 to 15-20*C
Thats only -13 to 77 *F (big difference to taxing in american summer where temps might be double that.
