Hey. Few days ago i recognized my coolant temp was up to 105-110 c°. When i got home car gave a warning message to check coolant. I checked and about 1liter is missing. I topped it up, next day i went for a city drive about 8-10km, the temperature was okay, but i loss about a half liter coolant. I did not see any smoke, car works as usual. Have anyone had the same problem? What can cause this?
