I had the AC blasting full throttle to get the fans on after getting caught in traffic with high ambient temp. The coolant temp was inching closer to the 1 o'clock.
You turned the A/C on to get the coolant temp down? Wouldn't that have the reverse effect? When you say 1 o'clock you mean inching towards 250? I've never had mine go much past the '8' (just left of noon on the clock dial) even while sitting on a hot/humid day in traffic for an hour with the A/C going. The secondary(?) fans turn on by themselves regardless if my A/C is on.
