PROBLEMS WITH TEMPERATURE Fiesta 2005

Good morning, I have a problem with a Ford Fiesta 2005 Motor 1.6 Zetec that I have not been able to solve it, I already rectified the head or butt, the thermostat was changed even perforations were made to the thermostat, the board of the head is changed, it starts well but it heats up, when I turn on the weather it is heated, the two ventilator speeds are still well I changed the ceite pump, the only thing that the time chain did not put in its brand that they bring only the crankshaft and camshaft marks aligned, I would like to know if that has to do with the fact that the engine is heated, the water pump works well. Or if you need another type of water pump, if someone already had this problem and could solve it, I ask for your help

What old wave, did you check that the radiator is not covered and that it has a free flow?, folded hoses and the return hose to the deposit is free? The fans work in second speed when the A/C enters?
greetings

You checked the temperature sensor can work but at different temperature range which causes the temperature to rise, a bad temperature reading can make the fans work after 80.90 degrees. What temperature do the fans turn on? Do not part of what the instrument picture marks greetings

We already check everything, the radiator is clean, there are no clogged hoses, the water passes the water, the fans turn on when the board indicator up to half, we already purge the air that is locked in the hoses, when the climate turns on the second speed too, and the indicator needle goes up the water is not thrown but the temperature is tapped but the temperature is high.

They turn when the indicator is halfway, I don't know how many degrees will be,
