You're welcome... I was always wondering that myself... Now that I have a engine performance data logging computer installed in the car I monitor many of those parameters when I'm at the track... The cooling system seems to work really well on this car... I've run it on the track in 105 degree weather and the highest ECT (engine coolant temp) logged was only 212 degrees... That was represented on the gauge at the midway point... From a cold start sitting at idle it will run about 183-185 degrees... It seems that the fan sensor trips at about 190 degrees...
