You are going to apologize to Davidfigueroam but I do not agree with you and it is for the following. If the thermostat was stuck closed then it would rise the temperature exits, it is not the case of our friend since he comments that accelerating low to zero, now if he were stuck open a little longer to reach his optimal temperature of operating Nadamas. In any case, in both cases the thermostat has nothing to do with the fact that he gets white smoke, now he who has his cracked cylinder head and is passing water to the combustion chamber does not necessarily be raised his temperature since the water continues to circulate throughout the system and accent on its cooling function, if this is happening then it will have an abnormal consumption of water since it is if it is if it is fled by the exhaust tube. How many vehicles did we see circulating through the streets and taking white smoke and those engines are never heated ... now in what I agree with you and express it in my first intervention is that our friend comments few data, for example it says that it works I shoot only when I am cold the engine or even being already at its optimal temperature and another thing the white smoke takes it away by dawn or during the whole day, these two data are important. Sorry but this is what I believe.
