After Citroen Elysee installed the thermostat, the water temperature was high, and the thermostat was fine. How to exhaust the air in the Elysee car with air?

Hehe, give it to me at five. I tell you, I am also the owner of the Elysee. Most of the water temperature in the Elysee is because the air in the water tank has not been exhausted. You unscrew the screw next to the brown plug plugged by the water temperature sensor, and then pour water into it like a bottle of water and a coke bottle until the water flowing out of the hole where the screw is unscrewed is in the shape of a water column. If not, tighten it immediately. It is convenient for the water room to release air, so let the air in the heating tank be the heating tank. Aren't there two pipes in the warm air tank? There is a small plastic cover at the top of the pipe. Unscrew the lid and add water until the water in it flows out in the form of water column, indicating that there is no air in it. This method is very simple. Oh, you can see that the two pipes leading to the hot air tank are right. This small plastic cover is easy to unscrew. It's hard to find because the cover has been replaced with a warm air outlet valve.
