Why is the car's water temperature high?

[LaAlyssa]

The reasons for high water temperature in a car: 1. Lack of antifreeze can easily cause air blockage in the water circulation, leading to excessively high water temperature; 2. The thermostat cannot open, which is also relatively easy to damage. If the thermostat fails to open, the antifreeze cannot form a large circulation, making it prone to overheating; 3. Cooling fan failure. When the vehicle is running at high speed, the generated heat cannot be transferred to the antifreeze in time, affecting heat dissipation and causing the antifreeze temperature to rise, boiling, and other issues; 4. Cracks in the impeller or loosening of the impeller from the pump shaft can slow down the coolant circulation speed, easily leading to engine overheating; 5. Using water as a medium for a long time can cause rust in the engine and radiator, resulting in poor radiator performance and high water temperature.
