Automobile Coolant and Antifreeze: Do you really know them?

In the maintenance of automobiles, coolant and antifreeze are two concepts that are often mentioned. However, many car owners are not very clear about their relationship and differences.

Is the engine coolant antifreeze? What's the difference between coolant and antifreeze?

First of all, we should make it clear that the coolant is not completely equivalent to antifreeze, but antifreeze can be regarded as a special coolant.

The main function of coolant is to absorb the heat generated by the engine when the engine is running, and radiate it into the air to keep the engine in the normal working temperature range. It can effectively prevent the engine from overheating and ensure the normal operation of the engine.

And antifreeze, in addition to the cooling function of coolant, also has the characteristics of antifreeze. In the cold winter, water will freeze and expand. If ordinary water is used in the cooling system of the car, the water tank, water pipe and other parts may break after freezing. Antifreeze can reduce the freezing point of liquid, prevent freezing in low temperature environment, and protect engine and cooling system from damage.

In order to show the difference between coolant and antifreeze more clearly, we can compare them through the following table:

project cooling liquid antifreezing fluid major function dissipate heat Heat dissipation and anti-freezing Applicable environment Normal temperature and high temperature environment Various temperature environments, especially low temperature environments. ingredient Usually a mixture of water and additives. Usually it is a mixture of ethylene glycol, propylene glycol, etc. with water and additives. Replacement cycle Relatively short Relatively long

In actual use, both coolant and antifreeze need to be checked and replaced regularly. If the coolant or antifreeze leaks or deteriorates, it will affect its performance, thus bringing potential risks to the engine.

In addition, different types and brands of cars may have different requirements for coolant and antifreeze. Therefore, when selecting and replacing, it is suggested that the owner refer to the manual of the car or consult professional car maintenance personnel to ensure the selection of suitable products.

In a word, it is very important for the normal operation and maintenance of the car to understand the difference and function between coolant and antifreeze. Only when properly used and maintained, can the engine of an automobile always be kept in good working condition and the service life of the automobile be prolonged.
