Nissan Tiida Hatchback water consumption

Hello, a greeting to all .... I have a Nissan Tiida 1.8 of 2008 that is consuming the water and not absorbed from the reserve and I change thermostate radiator FANIC and every day and a half the red light of temperature turns on since these cars did not come with temperature meter only the 2 lights a blue and the red ... If someone knows how to solve this problem or if I should disassemble the cylinder head

If Moteur Consomme de l'Eau, Sans Traces of External Fuites, Peut -être that caused her to go joint from Culasse. Bonne Chance!
