What is the reason for Jetta's high temperature?

The reasons for Jetta's high temperature are: 1: the temperature sensor is broken; 2. Loose fan belt and poor antifreeze circulation; 3. Insufficient antifreeze or too much scale, and the valve is not tightly closed, which leads to the blockage of the exhaust pipe. 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.
