Reply to "How hot is HOT?"

Nemo, For me, the mark before 230 is my ideal spot. My IR thermometer shows between 192-195 at the radiator inlet. It is about the same out of the engine. I installed a new radiator a couple of months ago. Last weekend I drove for 40 minutes through neighborhoods, never getting out of second gear & usually less than 30 mph. Outside temp was 93 degrees, high humidity. I was trying to see if I could get it to overheat. My gauge never budged from the mark. The IR thermometer confirmed the temps. Returned home & idled for a good 20 minutes. Gauge actually dropped & fell below the mark.
