Hello, I am currently having problems with cooling water loss with my Volvo 850. I describe how the problem started yesterday. I drove almost 400 km, after 150 km the cooling water warning light briefly lit up but a second later again. It then did not work again, until I came into a traffic jam and had to drive slowly. It then extinguished again, however, when I could drive again 100 / 120. After in the following time it again/ depending on whether I could drive slowly or faster, I made a rest, when I came back after 20 minutes, there was hardly any water in the liquid tank, so that I refilled. There was also no water under the car visible. I then drove the last 100 km without problems after I arrived I made a short break and drove another short distance on which he directly switched on the lamp again. When I wanted to drive back to my apartment in the evenings e the container was empty again. I refilled again. Also the short distance I had to drive of 2 km was enough that this morning almost no water was in it again. It is never a water leak or moisture under the car or on the container to see. I have now refilled cooling water 5 hours ago, since the car did not move, the water level has not changed. Does anyone have any idea what this water loss might be about? If there are still questions I try them best to answer. Greetings to John
