207 is nothing. My roommate's Passat ran at 210 degrees all the time. With the normal 1.1 bar pressure cap that I assume Honda uses on the Insight (since every other 92+ Honda is 1.1 bar) you should be good to around 270 degrees coolant temp. A lot of people think high coolant temps can result in warping the cylinder head, but they're only loosely related. Remember, aluminum doesn't melt until something like 1550 degrees. Anyway, 207 is nothing. I wouldn't worry until it's over 230 degrees or so. If you want to improve the radiator's cooling ability, just pour in some Redline water wetter.
