What phenomena will occur when the vehicle's water temperature is too high?

[LillianFitz]

When the vehicle's water temperature is too high, the following phenomena may occur: 1. The dashboard will display a warning for high water temperature or engine overheating. 2. The engine cooling fan will rotate at high speed, producing loud noise. 3. Engine knocking may occur. 4. In severe cases, it may lead to engine bearing failure, rendering the engine unable to start. Additional information: The vehicle's water temperature is an indicator reflecting the working condition of the cooling system. The engine operates best within an appropriate high-temperature range, as this optimal temperature facilitates better fuel combustion and reduces gas emissions.
