Gas adjustment and Antifreeze

1-I had the tube installed in 307 in July, the settings are very good, but since the weather was hot, the engine had set the engine temperature to be high so that it would switch to gasoline after the car started.

It is not important to wear it in summer or winter. The degree of switching to ideal gas is 30 degrees. In summer, the vehicle was switching to gas faster than 30 degrees. Therefore, you do not need to take any action. When it comes to antifreeze, I recommend red antifreeze. I think it is more reasonable to put the blue antifreeze in red antifreezes for 2 times more than the blue ones.
