When the weather is hot, the car runs a few kilometers and the thermometer reaches the red grid. What should I do?

You can tell what kind of car it is. Some cars need antifreeze. Because the default temperature in his ECU module is 1 10 degrees, the fan of the water tank condenser will be turned on. The boiling point of antifreeze is about 135 degrees. Regarding the temperature, you'd better ask the shop of your brand car. They will tell you what the initial size is, and then what the degree of each car is. Basically smaller than the red zone. The coolant you added meets the requirements of the vehicle. You can analyze the situation first, first, whether there is a lack of cooling liquid, second, whether the thermostat is broken, third, whether the water tank is blocked (you can directly see how the water circulation is, if it is too slow, it is blocked), and then there is a car body jam. If you see such a situation, you should check the coolant position. If you stop for a period of time, you should stop at the nearest repair shop or call the rescue phone in time for repair.
