But I was curious if you have calibrated/verified the readings on your oil and coolant sensors? It would be a shame to spend all the time and effort to modify your cooling system if it was something simple.

I flew the Cozy this after noon, and was very disappointed in the
temperatures. The OAT was 81, and the coolant read 225 on the temperature
gauge, and the oil climbed slowly to 207 peak. The coolant did come down
about 10 degrees when I throttled back at pattern altitude, but leveled off
there.

When I throttled back on approach the coolant was about 180 and oil 190 on
touchdown.

Steve,
You appear to be a very thorough and conscientious builder. But I was curious if you have calibrated/verified the readings on your oil and coolant sensors? It would be a shame to spend all the time and effort to modify your cooling system if it was something simple.
