What are the consequences of driving a car for a long time with high water temperature?

[SanHailey]

Continuing to drive when the water temperature is high can lead to deformation and damage of the cylinder block and cylinder head, and in severe cases, it may require replacement of new cylinder blocks and heads. The following are the reasons that cause high water temperature in a car: Cooling fan not working: The cooling fan may be controlled by a temperature control switch or a water temperature sensor. Insufficient cooling medium: Water or distilled water can be used temporarily as a substitute. Thermostat damage: If you want to remove the thermostat, the small circulation should be blocked to ensure that all the coolant is dissipated by the radiator. When installing a new thermostat, pay attention to the water hole. Radiator blockage: If the external blockage should be removed with water or air, internal blockage will affect the circulation of the coolant and generate pressure. Water pump failure: The impeller slipping or jamming causes the timing belt to break and the impeller to deform. Cylinder erosion: The combustion chamber and water channel are impacted, which will cause water or white smoke to be discharged from the drain pipe, resulting in frequent water shortage in the radiator.
