I have a 2011 Dodge Grand Caravan which seems to be using too much coolant. I've gone through a whole gallon of Prestone in the first 3500 miles and the Dodge Dealership mechanics were stumped by the problem after their pressure testing revealed no leaks. What should I do?

They can add a small bottle of dye to the coolant. After driving for a few days, they search with a black light including at the tail pipe. The dye will show up as a bright yellow stain that can be followed back to the source.
