What are the reasons for high water temperature in a sedan?

The reasons for high water temperature in a sedan are: 1. Insufficient antifreeze in the engine cooling system; 2. Malfunction of the thermostat, leading to high water temperature; 3. Abnormal operation of the cooling fan, resulting in poor heat dissipation of the coolant; 4. Malfunction of the water pump, causing it to rotate unsmoothly; 5. Engine oil entering the radiator. The solutions for high water temperature in a sedan are: 1. Pull over to the side of the road; 2. Cover the radiator cap with a repeatedly folded wet cloth, then unscrew the cap slightly to allow steam to slowly escape; 3. Monitor the dashboard water temperature gauge and, once the radiator pressure decreases, add cold water or antifreeze.
Having driven sedans for so many years, I've encountered overheating issues quite often. There are several main causes. Insufficient coolant is the most basic one, possibly due to a leaking radiator or evaporation from long-term lack of replenishment. If the water pump fails, the coolant can't circulate, causing heat to accumulate in the engine. When the thermostat gets stuck in the closed position, hot water can't escape, and the temperature spikes rapidly. A non-functioning radiator fan, caused by a loose belt or motor failure, prevents heat dissipation. Another common issue is a clogged or dirty radiator, which reduces heat exchange efficiency. I remember once on a long trip when the temperature gauge shot into the red zone, scaring me into pulling over immediately. Turned out it was due to an aged and slack fan belt. Now I've developed the habit of checking the coolant reservoir level monthly, looking for any oil leak stains, and regularly cleaning the radiator grille to maintain airflow. If you encounter a temperature warning light, never push through - pull over, turn off the engine, wait about 10 minutes before checking, to avoid costly engine overhauls. Driving safety should always come first. These hard-earned lessons can help you avoid unnecessary troubles.
