What does it mean when a car boils over?

When a car boils over, it usually means that the engine's operating temperature has reached a level that is too high for the normal working temperature range, thereby affecting the machine's normal operation and causing damage to it. An excessively high temperature typically refers to temperatures above 85 degrees Celsius, although different engine models have different standards. The higher the temperature exceeds the normal range, the greater the damage to the machine. Once you encounter a car boiling over, the first thing to do is to pull over, but do not turn off the engine. Let the engine idle for a few minutes to allow the water temperature to decrease slightly on its own, then turn off the engine and wait for it to cool down naturally. When you see smoke coming from the hood, never pour cold water onto the engine, as this can cause severe damage to the engine.
As an old-timer who frequently tinkers with cars, I've encountered several instances of engine overheating. Simply put, it's when the engine temperature rises too high, causing the coolant to boil and emit steam, just like water boiling in a pot. This is usually due to issues with the cooling system, such as insufficient coolant, a malfunctioning radiator fan, or a stuck thermostat. If not addressed promptly, the engine could suffer from cylinder seizure or even total failure, resulting in frighteningly high repair costs. Whenever I notice abnormal temperature gauge readings or steam coming from under the hood while driving, I immediately pull over and turn off the engine. It's crucial not to rush to open the hood—wait for it to cool down naturally before checking the coolant level. Regular maintenance is key; I change the coolant every three months and avoid long-distance driving in hot weather.
I remember when I first started learning to drive, I had no idea what 'engine overheating' meant. That time when white smoke started coming out from under the hood halfway through the drive, my heart nearly jumped out of my chest. Later, my instructor explained it was caused by coolant boiling due to excessive temperature. Possible reasons included a broken fan or leaking pipes, which can be quite dangerous. Since then, I've developed a habit of checking the coolant level every week. I stay alert whenever the temperature gauge shows abnormalities, and I always wait at least ten minutes after stopping before handling anything to avoid getting burned.
Having driven for many years, 'car boiling over' simply means the engine is too hot, causing the coolant to boil. Once it happens, the temperature gauge spikes or steam emerges, and you must stop immediately to prevent engine damage. The causes usually stem from a faulty cooling fan or coolant leakage. The solution is straightforward: safely pull over, turn off the engine, and wait patiently for about half an hour to cool down before proceeding with a vehicle inspection or adding coolant.
