Thanks for both responses. FYI, the repair my husband made was over a month ago. He said the same thing, give it time to burn off but a month later it is still there. So I am guessing from what you area saying there is another leak we can't see. Ugh. Can I say I hate this vehicle. We replaced the transmission after less that 50,000 miles, radio does not work, the heat is so uncomfortable in spring/fall when no systems are on and now this. (this is the short list). Sorry, I am frustrated.
