Você não diz se mudou o termostato ou não? Eu mencionei isso no meu primeiro post. Eles podem ficar "pegajosos" e parecem funcionar bem às vezes. Remover o termostato para descontá-lo é um método de diagnóstico usado regularmente. 

Além disso, a maneira mais fácil de verificar a entrada e saída de mangueira pode indicar que não há fluxo devido ao fechamento do termostato.

The thermostat has been removed.

If anyone has the repair maintenance manual, could you send it?

Sorry, WHAT???

Height of valve control block?

Someone has the height of the original head.

Check your radiator has good flow and also check the thermostat isn't sticking. Any radiator that's even partially blocked can kill engines. Could explain why your cooling fan has no issue controlling the system temperature in the city but fails on the open road as higher revs = more heat, failure to expel heat = overheat. Also check your coolant is rich enough and not had water added too many times.

I already tested the radiator. And the cooalant fluid is normal

A few months ago maintenance was done on the engine of my Journey 2.7 and again I had an engine problem that overheated and damaged. It was heating only when in high rotation on the road, inside the city nothing happened. They could help me figure out the problem, the water pump had already been replaced.

Thank you all

after changing the temperature sensor, we found the resistance of the problem fan and also the reservoir cap that was opening the safety valve before the pressure.

Se você fez todos os passos "básicos" (e mais do que escreveu), é hora de aceitá-lo. Embora eu tenha recebido uma bomba de água ruim uma vez. Eu tinha outro veículo que fazia o mesmo, eu substituí algumas coisas Isso Me manteve o aquecimento. Finalmente, aqueceu uma vez demais (enquanto eu estava testando), que o motor  finalmente desistiu. O custo foi de US $ 3500 para solucionar, o problema era um sensor de US $ 29 que eu não sabia sobre ... e nem sequer havia escrito sobre nenhum fórum. Eu simplesmente não queria pagar a carga de diagnósticos de US $ 85 ... nunca mais. 

Which sensor did you change?

I have Jouney 2011 is overheating only when it is in high rotation, the thermostatic valve has been removed and replaced the water pump and it still keeps heating, the fan is normally turning on. Has anyone had this problem?
