Hello dear community, Twingo 1995 C 06 Motor: C3G yesterday I drove to the 200km with our Twingo. All the time with normal driving mode at approx. 16° outside temperature. Then I kicked it briefly and then a short time later my water temp. display went on. Directly down and looked. Container was still full and at the water pump it hissed out. Seal -> leaks. (it then souped out whenever) Then everything was built apart. Pump and hoses as well as coolers respectively. Thermostat in tuchkopf and this opens also at 89°. The evening before, I already noticed that the heating only gets warm sometimes or stayed cold. Was there only air in the system? And how does this come in? Because as I see it, the heating is still in the “small circuit”. And what is the hose that goes from the water pump housing to the carburettor? LG Phil
