The position of the coolant has dropped in winter, why is the antifreeze used fast in winter?

There are two main reasons for the decrease of the coolant position in winter. One is that the warm air is often used in winter, which causes the antifreeze to evaporate. This is a normal phenomenon; the other reason is that there may be leaks in the water circulation. There are two types of external leakage and internal leakage. External leakage is mainly to check whether there is a large amount of water mist in the upper and lower water pipes, cooling system and windshield glass in the case of external circulation, while internal leakage is to see whether there is red residual liquid in the exhaust pipe.

In winter, the antifreeze is used quickly. In addition to the possibility of leaks, there are also the reasons mentioned above that the warm air is frequently turned on, which causes the antifreeze to evaporate, so the use is faster.

Antifreeze is called antifreeze coolant, which can prevent the coolant from freezing and bursting radiator and frost damage to the engine cylinder block or cylinder head when parking in cold winter. However, many people have a misunderstanding, thinking that antifreeze is only used in winter, in fact, antifreeze is used throughout the year.

Antifreeze also has a life cycle. Generally, the life cycle of antifreeze is about 2 years or 40,000 kilometers, but for some luxury cars (such asBenz), the use of car antifreeze can be up to 10 years, and for some long-running vehicles (such as taxis), it is best to replace it once a year. However, the specific service cycle should be judged according to the maintenance manual and the actual situation.

When using antifreeze, it is forbidden to mix other different models and brands of antifreeze, and it is also forbidden to mix with water. Because mixing with other antifreeze fluid may cause a chemical reaction, the antifreeze fluid loses its effect and even damages the engine. The water mixing will produce scale, affect the heat dissipation effect of the radiator, block the water channel, etc., causing the engine to malfunction.
