The coolant temp is always the highest after driving the car in very hot weather, parking it for about five minutes and then restarting. If it becomes a big problem this summer, I will take the cool harness out of the system. As I said above, though, it's only happened occasionally. I like the fans coming in at the lower temp because, even on a very hot day, I rarely see 110 when driving.
