Hello everyone! Since the search can’t help me and I seem to have a mistake in thinking…… I have to ask you. I changed the coolant flange at my seat, including seal. After that I wanted to ventilate the cooling circuit, but after I start the engine, both fans start. Engine does not get warm and can not be ventilated Coolant is felt, but air inside the temperature sensor is plugged (has worked before the change) What am I doing wrong? Is there a fan screw or must be filled with vacuum? Can the sensor break when changing? Lg Daniel Seat Altea XL; Built 2009; 1,9Tdi BLS Motor
