You really don't want to make it habit of getting the temperature much above boiling to start affecting the chemical makeup of the fluid. It definitely is affected by excess heat such as temperatures up to 250°F or so.

I would be interested in knowing more info on the peculiarities of antifreeze.

I honestly wouldn't recommend maintaining temps of 250°F, but I would hope holding steady at 200°F would be fine.....is this a bad assumption?

And I think having the ability to control air flow is starting to sound way cool, especially considering the cooler temps heading our way this time of year.
