1, the engine cooling system lacks antifreeze.
2. The thermostat in the engine cooling system is out of order, resulting in high water temperature.
3. The cooling fan in the engine cooling system is not working properly, resulting in poor cooling of the coolant.
4. The water pump in the engine cooling system is out of order, and the pump does not rotate smoothly, resulting in poor liquidity of coolant. The solution to the high water temperature is: park the car on the side of the road, cover the water tank cover with a wet cloth that has been folded many times, unscrew the water tank cover with a small crack, and let the water vapor drain slowly; Observe the water thermometer on the instrument panel, and replenish cold water or antifreeze after the water tank pressure drops.
