Actually, I hadn't seen this written anywhere until now, but the other day I started the car to back it up in the driveway, and when i shut it off, the fan stayed on. Good to know that its supposed to do that, in some function. However, I doubt the water temp was that high, and I know the air temp wasn't up, but the ac may have been on. I started the car, turned it back off, and the fan went back to sleep.
So, we learned there is a cooling feature that is a tad glitchy.
Oh, and the hood thing is accurate, very good design. Fully functional
