When it is zero outside if I leave my car idling and come back to it in 15 mins, the cabin is warm (from leaving the heat on lowfan/Max) and the engine is at about 82C, once I start driving it rises to about 84C, and stays there, even when its zero out. And its real toasty in the car

But if I crank up the fan to High or defrost, the engine temp will fall a little bit, to around 81C. I rarely have to put the fan above low, as the drifting/slow air from the vents is more than warm enough to make it hot in there. But yes, mine gets to the very same operating temp at 0 degs out that it does when its 90 out.

It does take a little longer to get there (maybe 2.5 miles) but it does it.
