Mysterious coolant

Great but "Gee Whiz" I can't believe you could not SMELL that much leaking........and it usually doesn't take much to smell and to fog up the windows from the defroster.
Never smelled a thing and I've seen it fog the windows just never made the connection until you all mentioned it. That's why when you all mentioned it, I decided to yank it out and see. Found a box full of my coolant but somehow not leaking into the passenger compartment
