VITZ 1SZ Motor Heating

Hello everyone, my car began to heat, change the radiator cap because it didn't work. He took the mechanic, a water pump changed (it dripped) according to him the cylinder head was fine, the thermostat or thermoswitch was fine, I tried it and continued heating, the sensor turned on but intermittent. He returned to the mechanic, did a cleanliness of the radiator externally and internally, when he proves it - he says - that everything goes well. The issue is that it begins to boil and lose water, as you are losing I can not yet put on it, every day I have to increase some water, there are no leaks there is nothing. In the Scaneo everything comes out ok.

Help me please this problem that brings me crazy.

Good afternoon friend, the first thing you have to check is whether it does not come out of the exhaust if it is so cosuming it by the pistons the Evempra would have to recctify cavezas because when it comes to heating an aluminum caveza tends to bend or damage the packaging of the caveza other obfion Purgen. Greetings I hope it serves as a reference

First of all, if you put water, it is unveiling somewhere, if you do not fall to the ground, you have opsions, that it is entering the combustion camera, which is mesclanding with the oil, that the oil is mixed with the water, and that between comprehension in the refrigeration system, any of those is a button, now Czech that between the scribeer when appropriate and that the system is well bleeding

Friend:
Water is not mixed with the oil, the electrventilator works more, that is, when the engine is heated, it starts working longer. The butt is fine, yesterday my mechanic did the cleaning of the catalyst of my escape and told me to try it again, the truth is that all "arrangements and changes" so far have not worked, since everything works well, but the matter is that it overheat a lot and makes it begin to boil the water of the radio and therefore lose water. I don't know what the problem will be.

It is very likely that the cylinder head or the Board is suffered from the previous problems. I would advise you to disassemble and review the packaging and projection of the cylinder head
