When air is compressed it does NOT get colder, it gets warmer just like anything else that is compressed. Air only gets colder when its decompressed, such as a co2 cartridge that gets colder when being used or letting air out of your tire. The coolant is there to keep the throttle body from freezing over in sub 32 degree weather, effectively acting as a heater to the throttle body since the coolant is around 200 degrees or more when warmed up. For this reason it is only to be used in areas that never get below 32 degrees, Florida for instance, since there is no chance it can get frozen. I do not have a degree, but I took multiple physics classes in high school and college.
