I heard if you replace the radiator cap with the 1.6 Kawasaki cap it would stop the loss of coolant. Well, I replaced it and it still looses coolant. I can see it run out the overflow hose but it isn't like it is under pressure like it would if overheated. The engine isn't overheating. I cannot find any other wet spots or leaks. The oil has no water in it. Has anyone else had this problem? How did you fix it? Any ideas? I thought about doing a leak down on the engine to rule out the head but wouldn't there be either be water in the oil or oil in the water?
