What are the situations that can cause a car's water temperature to become too high?

[McKylie]

There are several situations that can cause a car's water temperature to become too high: 1. Insufficient coolant; 2. Radiator leakage; 3. Cooling fan malfunction; 4. Thermostat sticking or failure; 5. Water pump damage. Solutions for high car water temperature include: 1. Check the temperature difference between the upper and lower radiator hoses; 2. Inspect the thermostat's opening degree and whether the water pump has speed loss issues; 3. Thoroughly clean dust between the condenser and radiator using high-pressure air; 4. Use original equipment manufacturer (OEM) parts when replacing or adding antifreeze; 5. Check the return water flow in the upper return hose of the antifreeze reservoir. Precautions for high car water temperature: 1. Slow down and pull over to the roadside while driving, but do not rush to turn off the engine; 2. Avoid splashing cold water on the engine when cooling it down.
