I have a 180 and I don't go above the O in normal driving. In winter, I sometimes didn't even get into normal range on way to school. I have added some redline water wetter and now, when the t-stat opens at 180 when doing aggressive or slow driving the temp actually drops back down unlike it used to. My low speed fan has worked only once since I've owned the car, so I can't idle for long or the engine gets real hot and the high speed won't kick in until it gets out of the normal range.
