I still think there was some kind of snafu with the plate. The way I understand it, it would close back up again as it cools down, so you shouldn't have temps under 180 on the freeway. Again, this is all hypothetical to me since I live in a place where summer goes until October. Someone from a more normal climate may be able to help more.
