2nd time - anti-freeze... gone! 2 checks performed, 2 different places, no leaks. Last summer, my ac went out (22K miles). Had it checked... nothing wrong... woke up this morning to a puddle of sludge (A/F) in my driveway. This is the 1st time it's visible. Praying it's just the change from freezing weather to 50 degrees in a 24 hour span!
