Short answer, I think you won't hurt anything at 210. All the modern cars run over 200 it seems, and they achieve long life. Also being in Houston, I understand your concerns. Mine won't top 194, and most of the time stays below 187. I went to a 170 degree thermostat so that in the winter it doesn't drop down below my warm up enrichment settings, which is 160. With a 160 thermostat it would drop to 155 in the winter... I have an aluminum radiator, with 2 1" tubes, and dual electric fans. I don't remember their diameter, they're mid 90's Dodge Intrepid fans. Most of the year low speed will keep it 185 or less. But high speed is set to come on at 194, and that will happen occasionally in the hottest part of the year. High speed takes it back to the mid 180's and then it cycles back to low. The ECU has made a difference by allowing timing settings that wouldn't be possible with a distributor, and the ability to control the fans optimally.
