Feb 2005 Carnival, brand new, auto box, 10,500k. It's losing about 750ml over a 3 week period with no obvious leaks inside the car (heater) or in the engine bay. No leaks, no smell, nothing. It's been back to the dealer twice and they can't find anything...last time it was a "air lock". Is there an "additive" that mixes with the coolant and they can see a leak using ultra violet light? or did I see that on Star Wars?
Suggestions please. :blush:
