what is this breakdown or i will be crazy please help

The main problem is the water reduction of the car. first they replaced the exhaust gasket and the water plugs, then they said the cylinder gasket, but neither oil nor oil into the water mixes. I just squeezed the car today so it looks like if it is missing from the barrier or we can see. but I opened the hood on the same level. I went home 3 hours later I went down, almost half a liter of water decreased. Where did this water go now ... I couldn't figure it out and now every master says something different. I do not want to have the roller removed. please help ...

In addition, the temperature indicator does not play from anywhere, when I increase the temperature, the fan turns on in its normal place. please help ...

Is there any wetness in the mats and there should be no messing in the heating pipes

No master, there is no wetness. I traveled 5000 km in summer, min. The water level is slightly below the line. & nbsp;

Did you look at the thermostat? There may be a slight infiltration in my car, there was infiltration from the thermestate, water was decreasing. When heavy maintenance was done, we took over the thermostat right now.
