In the summer (without a grille block), the A/C and city driving pushes the envelope to 220F under normal circumstances. The fans kick-on at a varying degree of temps -- from 206 to 218.
But, in the essence of longevity, I'm trying to stay below 230F anymore. Parked in the garage after a 240 run, it just smells hot. At her age, Teggy doesn't need any more stress than she's under already
Pulling-down 3 MPG may not be worth the heat...
