Good morning to all. With curiosity I observe that my Peugeot 306 1800 CC of 1995, has no auxiliary water tank. In the part where the radiator nozzle goes, the manguerite comes out that in all the cars is directed to the auxiliary water tank, to provide themselves from there if necessary, however, in my car, the hose leaves but it does not go anywhere, it simply ends and now. Lately, water consumption has increased and according to the use of the previous day, in the morning I can adjust almost a gallon of water to the radiator. Can you please tell me if these cars come without the auxiliary water tank or mine lacks? Thank you so much.
