Just a heads up. I was driving around today and noticed a coolant smell and thought oh great somethings leaking. When I popped the hood to my amazement the coolant cap was gone! After looking around for a while I found the cap down on the underbody splash shield. Nobody not even me has touched that cap, so it was apparently never completely screwed on. Check your cap and make sure it clicks 1 time when fully tightened. On the positive side at least it was just the cap.
