Peugeot 207 Sudden Temperature Rise

My vehicle is peugeot 207 2008 Model Gasoline. When the temperature of my vehicle is gone a little, especially when the speed exceeds 90 km, the temperature rises suddenly and it gradually decreases when the gear shifts to the blank or the fan turns on. It rises fast and falls fast. The thermostat knuckle timing belt has changed but the fault continues. The heat rises to the top and falls back until it draws to the right. What is the problem? I always say different things to whomever I take it. If there is a good master you know in Çorlu, I am also open to suggestions.

temperature is normal around 90 100. peugeot likes to work hot.

Generally, the temperature is already 105 and 110. The fan is running. If a little speed is made, it goes up to the top and sometimes even warns to stop.

When I say speed is 100-110. Thermostat timing switch has been changed. We look at the pipes, they are hot.

If the temperature rises as the speed increases, the problem is definitely the circulation engine. Do not look for the problem elsewhere.

The heat in the city is always at 110 da. When the speed increases to 100 km or when the vehicle gets a little harder, it shifts back to 110 and 105 in front of the fans. In this heat problem, I have never done excessive speed with the vehicle once. The temperature gauge comes out and falls fast

This high temperature is not normal, at a constant speed of 100-110 km. When the air conditioner is turned on in the city, it comes to mine

Yes, it is not normal, what could be the problem?

Is there an antifreeze in the vehicle. Does water decrease? does the fan turn on? Maybe the 2nd Degree fan does not turn on?

Since the temperature of the car is too high, there is a decrease in water. But this water reduction does not always happen. The 2nd degree fan opens at 110 or so

Is there a situation such as fluctuation stop at idling speed? Or like opening a timeless fan?

The big fan hurts at 95. I did not understand the incident called idling because I did not know the car technical features very much.

It stands at 1 fixed, but again I look carefully

I am rewriting, it is definitely related to the circulation when the speed increases. The circulation cannot fulfill its duty. Did the recirculation engine change as the timing changed? If it is changed, is it a subsidiary industry
