I drove through a washout and water reached over my hood. A Mile down the road we stopped and steam and a steady stream of water was pouring from under my radiator. Three guys were all standing around telling me I had a radiator leak or broken hose as it kept coming steady for 5 minutes straight. I kept telling them no way it was radiator fluid as it was clear. To their credit it was hot. After 5 minutes it stopped finally. Checked the radiator... completely full all red in color. Their must be some serious collection capacity for water in the JK.
