Over Temperature Problem?

Hello, I have a 2007 model peugeot 207 1.4 diesel vehicle. While driving the vehicle normally, it does not exceed 80, but when I enter the traffic, it is approaching 90, but I did not see that it is 90 or 90, but it is approaching 90, which is not normal. It had been overheating in Antalya before and the antifreeze pipe etc. has changed, but it still misses 200ml of water every 2 months, if only a little. Do you think I should be afraid of the intermittent heat in this traffic, it creates paranoia once I get stuck on the road.

No problem, normal situation. The most efficient operating temperature of the engine is 90 degrees.

Hello fellow countryman. There is an evaporation valve behind the engine water tank. Make sure the valve tube is connected. Check whether the air intake hose comes out from the back of the engine. If the valve cable is disconnected, it is very normal to decrease the temperature and water while traveling, and if the air suction plastic is out of the rear, the temperature rise in traffic is very normal. Good forums ..

Have your vehicle's thermostat checked. If the engine cannot reach the ideal operating temperature, the thermostat may have remained on. A similar situation had happened to me in Opel Vectra.
