This happened with my friend's Mercury Sable... EXACT same problem, the smell was so sickly sweet. I can't remember what the problem was, but I don't remember it being a cheap fix.
I'm not sure if the coolant leak is related, though it doesn't sound like it. I'd look into fixing the coolant leak regardless.
