113,000 miles and I'm already starting to smell anit-freeze from under my car. No leaks....yet. What's the deal?!? I power washed the engine (to see if it was just some old fluid that got splashed up from the road or soemthing but it still smells) My car is a born and raised So Cal car, and I have changed my fluid every year, regardless of miles. It doesn't overheat or anything. Anyone else had this issue? Could it be the cap just needing to be replaced? Watchall think?
