What happens when a car runs out of water?

Continuing to operate a car with an empty radiator can lead to engine failure. Here is an introduction to the car radiator: Introduction: The car radiator, also known as a heat exchanger, is a key component of the car's cooling system and an integral part of the car engine. Function: Its purpose is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator where the heat is dissipated, and then returns to the water jacket to complete the cycle, achieving temperature regulation. Composition: The car radiator mainly consists of a radiator core, water pipes, cooling fins, an upper tank, and a lower tank. The radiator is connected to the upper and lower tanks via water pipes. When hot water flows from the upper tank to the lower tank, it cools down. The cooling fins form air channels, and with the help of the fan's suction and the relative wind speed when the car is moving forward, a large amount of cold air passes through these channels, absorbing the heat from the coolant in the pipes and then releasing it into the atmosphere.
I once ran out of coolant during a long-distance trip, and the engine temperature gauge shot straight to the maximum. Soon after, smoke started billowing out, so I quickly pulled over to check. The cooling system had barely any water left, likely due to a leaking radiator or excessive evaporation. As a result, the engine overheated, damaging the cylinder head gasket and nearly causing a blown engine. It cost me thousands to repair and delayed important plans. I recommend making it a habit to pop the hood every week and check the expansion tank's coolant level. If it's below the minimum line, top it up with the specified coolant—don’t just use plain water. Also, watch for signs of leaks, like green or red fluid stains on the ground. Regularly replace the coolant to prevent corrosion and freezing issues—safety first.
