Hello, I have for some time a huge water loss at my Kia Carnival 2.9 CRDi (year 2004, 99tkm). The compensation tank is completely filled, in the hose I pour about 1.5 liters per 300km. The engine temperature tends to be lower than usual, the fan runs sometimes even if the temperature according to the display is actually still too low and the heating does not bring any more power. In the back it no longer heats…. mostat replace, timing belts and water pump in August 2009. Error memory does not contain any information and Kia has had a pressure test of the system without any results. I thought it was the cylinder head seal, but there is no water in the oil and there is no white smoke from the exhaust. Under the vehicle (garage car) there are also no large puddles. Does anyone have an idea what this could be???? Have bought the car in 2004 and had all service maintenance done. Thank you! Mark us
