Antifreeze is an important part of a car's cooling system, preventing water from freezing at low temperatures and protecting the engine. Antifreeze not only prevents the vehicle from freezing in cold weather, but also improves heat dissipation and keeps the engine running. Therefore, it is important to understand the life cycle of antifreeze and how to replace it. Here are two situations in which antifreeze needs to be replaced:
1.The quality of the antifreeze decreases.
The ingredients in antifreeze include additives such as preservatives, rust inhibitors, etc., which are continuously depleted over time, resulting in a decrease in the quality of antifreeze. When the quality of antifreeze decreases, its antifreeze and anti-corrosion properties will be weakened, and it may not be effective in preventing vehicles from freezing in cold weather. It is advisable to check the quality of the antifreeze regularly, and if you notice that the antifreeze has become lighter in color, has dropped in freezing point, or has lost its flowability, it should be replaced in time. In general, a decrease in the quality of antifreeze can lead to a shorter lifespan, and it is recommended to replace it every two years.
2.Antifreeze leakage.
Antifreeze leakage is a common malfunction that can be caused by a ruptured antifreeze jug or water pipe. If the antifreeze is not replaced in time, it may cause the water in the cooling system to leak and the engine to overheat and be damaged. Therefore, if you notice a leak in antifreeze, you should stop the car immediately and check the cause of the failure, and if it is determined that the antifreeze pot or water pipe is broken, you should replace it with a new antifreeze and refill the cooling system.
When changing antifreeze, there are a few things to keep in mind:
1.Choose the right antifreeze. Choose to use the same type of antifreeze as your vehicle to avoid damage to the engine.
2.Cleaning the cooling system. The cooling system should be cleaned before replacing the antifreeze to remove dirt and sediment from the cooling system.
3.Properly fill the cooling system. When changing antifreeze, it should be filled in the correct order and method to ensure that the antifreeze can flow adequately.
4.Exhaust. After replacing the antifreeze, the air in the cooling system should be exhausted to ensure the proper operation of the cooling system.
In conclusion, antifreeze is an important part of a car's cooling system, protecting the engine from freeze damage and overheating. If you notice a drop in the quality of the antifreeze or a water leak, it should be replaced promptly. When replacing antifreeze, you should choose the right antifreeze, clean the cooling system, properly fill the cooling system and exhaust air to ensure that the cooling system is working properly. At the same time, it is also recommended that car owners regularly check the health of antifreeze, and if it is missing, it needs to be added in time. Only the correct use and replacement of antifreeze can ensure the normal operation of the car and extend its life.
