Why do car fumes get released when it gets hot?
When it gets hot outside, some of these toxic fumes start to get stirred up and released again.

There are so many chemicals in an average car, causing such a variety of problems, that there’s no point in listing them all.

Why does my car smell like antifreeze when I run heat?
I filled up the antifreeze and it dropped maybe one-half inch. There is NO residue on the windshield or windows, and no leaking antifreeze through the floor heating vents.
