Where does the cool stuff go

I have a 97 Mercury Sable, and I am trying to find where you put the Freeon (spell?). I have a kit, but cannot seem to find where you would put it, anyone out there able to enlighten me?

Do yourself a BIG favor and stay out from under the hood. You could hurt yourself badly. It’s not worth it.
