while up in tallahasee, the family decided to go out to eat. We left in the middle of rush hour, and were driving in stop and go traffic for around 40-45 minutes, with the a/c blasting and the car never going faster than about 15, and that was only for short spurts at a time. The ambient temp was about 90F. As we went on, the temp guage slowly climbed to around 100C, and stayed there. I noticed in traffic down here when i'm stopped at a light it's not unusual for the temp to go to about 90, and once i'm moving it drops right back to about 82 or so. Is this normal or do i have a potential problem? This is with the a/c on, without the a/c on it will sit and idle for years in a dessert without going much higher than 85-90C. Radiator was replaced about 9 months ago, as were the hoses. While driving on interstate etc, the temp is between 80-82 reguardless of load, a/c or not, and speed. thanks in advance
Ryan
