What is the reason for the high temperature of Volkswagen Jetta?

A few days ago, some netizens asked Bian Xiao, "What is the reason for the high temperature of Volkswagen Jetta?" Now Bian Xiao will explain it to you. The reasons for Jetta's high temperature are: 1, the temperature sensor is broken; 2, the fan belt is loose, and the antifreeze circulation is not smooth; 3, antifreeze is missing or there is too much scale, and the exhaust pipe is blocked because the valve is not tight. All of the above may lead to an increase in the temperature inside the car. The high temperature of the car will cause engine damage, because the engine is very hot when working, and it is cooled by coolant, cooling fan and water tank. If there is no coolant, the working temperature of the engine will be higher and higher. Because of the principle that objects expand with heat and contract with cold, the internal parts of the engine will expand, which will lead to the failure of engine cylinder pulling. Common fault points of engine at high temperature are: 1. The lack of antifreeze in the engine cooling system may be the leakage point of the engine, such as water pump leakage, pipeline damage, water tank damage and so on. 2. The thermostat in the engine cooling system is out of order, resulting in high water temperature. Because the thermostat can't be opened, the flow of coolant in the engine is blocked, so the coolant temperature is too high. 3. The cooling fan in the engine cooling system is not working properly, resulting in poor cooling of the coolant. Therefore, the water temperature light is on, which leads to the high temperature of the coolant. Million car purchase subsidy
