Difference between coolant and tap water

The cooling system of an automobile is a key component of the healthy operation of the engine, in which the coolant plays a vital role. It is different from daily tap water,antifreezing fluidIt stands out because of its special composition and color. Usually, antifreeze is red or green, which contains ethylene glycol and other components. It is more stable than water and has low volatility, which can effectively cool the engine.

Different from tap water, adding antifreeze can prevent the engine water channel from corrosion and blockage, thus ensuring the smooth operation of the cooling system. Coolant passes through two circulation paths inside the engine-large circulation and small circulation, which helps to dissipate heat. At the initial stage of engine start-up, the small cycle ensures the rapid temperature rise, while the large cycle further reduces the temperature of the engine through the radiator water tank after it reaches the working temperature.

However, coolant is not eternal, and it needs to be replaced regularly. If it is not replaced for a long time, the performance of the coolant will gradually weaken, the freezing point will increase and the boiling point will decrease, which may lead to overheating of the engine. Once coolant leakage is found, the leakage point should be found and repaired in time, otherwise the safety of the engine will be endangered. When replacing coolant, be sure to choose professional service to ensure cleanliness and quality of new fluid.

Generally speaking, coolant is an important part of automobile cooling system, and its selection, use and maintenance are directly related to the health and performance of the engine. Ensuring regular inspection and replacement of coolant is the basis for maintaining a good running state of the vehicle.
