Why does the water level in the radiator keep dropping even when the water temperature is not high?

Even when the water temperature is not high, natural evaporation occurs, leading to a gradual decrease in water level, which is a normal phenomenon. Below is relevant information about the radiator: 1. Concept: The car radiator, also known as the heat exchanger, is a key component in the car's cooling system. Its function 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 circulate, achieving temperature regulation. It is a part of the car engine. 2. Working Principle: The radiator is a crucial component of a water-cooled engine. As an important part of the heat dissipation circuit in a water-cooled engine, it absorbs heat from the engine block to prevent the engine from overheating. Due to the high specific heat capacity of water, the temperature rise after absorbing heat from the engine block is not significant, so the engine's heat is transferred through the liquid circuit of the coolant.
I found that the radiator frequently loses water but the temperature remains normal, which is mostly due to a slight leak in the system. I encountered a similar situation with my own car. Upon careful inspection, I discovered that the radiator connector had aged, and the water seepage was not obvious. The water temperature didn't rise because the leakage was small and didn't affect cooling temporarily. It could also be due to worn cylinder head gaskets, where water leaks into the engine oil, leaving a milky trace on the oil cap, and in severe cases, causing engine damage. Or the water pump seal might fail, leading to a ticking drip. I suggest checking the water level and any wet marks under the car every two weeks and repairing it as early as possible. Don't be like me, who delayed until the radiator was completely empty and broke down halfway, regretting it deeply. Now, I maintain this habit, saving both money and peace of mind.
