What should I do if the car's water temperature is too high?

Methods to deal with high car water temperature: First, slow down, then pull the car over to the side of the road. Do not rush to turn off the engine; instead, keep it idling for a while. Put on gloves, place a wet cloth over the radiator cap, and unscrew the cap slightly to allow steam to slowly escape. Once the radiator pressure drops, add cool water or antifreeze. High water temperature is usually caused by water pipe leakage or insufficient coolant. In such cases, you can add distilled or purified water as an emergency measure and arrange for repairs when convenient. Just be careful not to open the radiator cap when the engine is hot to avoid being scalded by the high-pressure steam inside. If the water level is sufficient, check the fan behind the radiator. Even after the engine is turned off, the fan should still be running when the water temperature is high. If the fan is not moving, try turning the fan blades manually to see if the motor is stuck. Normally, the blades should turn easily. If the motor is fine, check the fan fuse. A faulty thermostat can also cause high water temperature. Once it fails, it cuts off the coolant circulation. If you feel a noticeable temperature difference between the upper and lower thick rubber hoses of the radiator when touched by hand, it indicates a faulty thermostat that needs to be removed and replaced.
