Hello, I would like to have a problem. For a week we have had a daily water loss of a little more than a litre. Now my wife was on the road again today and told me that the temperature was almost 100°C at about 120km/h and how she is off the highway and stood at the traffic lights, it went further up to over 100°C. She then turned on the heating and the temperature went down slowly. Later I drove myself by car (with filled up W Asser tank) and when I drove the car warm, I went on the track and accelerated to 140km/h. The display shot in the red area, I immediately slowed down again and the temp went down slowly again. When I arrived at home, the water tank was almost empty. An hour later I ran the car with an open cooling system until it had operating temperature. Then filled up containers and lid on it. Let the car run further and it built d Then we turned the engine on about 3000upm and suddenly boiled the water in the container (white bubbles) and came out in not very small quantities on the lid again. What can this be about????????? I have no idea what this could be….
