Automotive antifreeze replacement cycle

It’s summer soon, summer is coming, and the temperature is getting warmer every day. For the owner, is there such a shame that, in the summer, you can not use antifreeze. If you know the full name of antifreeze, I believe that there will be no such idea. The full name of the antifreeze is antifreeze coolant. Yes, there is a cooling effect. The summer temperature is high, and this cooling effect is very important. Therefore, antifreeze is not only used in winter, but used all year round. So, what is the antifreeze replacement cycle ? Let's take a look at the introduction of Xiaobian!

For the car, there is a saying that is good. "Three points, seven points," which means that the maintenance of the car is critical. After the car has been used for a period of time, it is difficult to avoid the wear and aging of the internal parts, so regular maintenance and replacement of the corresponding parts are necessary.

Introduction of antifreeze coolant

Coolant function: cooling, lubrication, anti-corrosion, anti-freezing; how long to replace depends on the formulation of the coolant, silicate, silicon precipitation can protect aluminum, but the precipitation life of silicon is about 2 years, so 2 years Replacement once, the organic acid usually has a long life. If the vehicle is certified by the original factory, the organic acid can be used for 4 years or 20W; the coolant can not be used over time, then the aluminum parts, rubber parts, pumps In addition to the control of sediments, in addition to the formulation of the coolant, the choice of boiling point is also very important. The domestic common antifreeze can only reach 107 degrees, the good point is about 113 degrees, and the boiling point of imported products is usually It can reach 129 degrees, and all of the above are ethylene glycol based products.

Antifreeze coolant replacement cycle

Manufacturers have a clear description of the maintenance cycle of automotive parts, and the use of antifreeze is also introduced. The general manufacturer's recommendation is to replace the vehicle antifreeze every two years. We also saw the “recommendation” because each person's car is different and the replacement time will be different. For those vehicles with short running times, it is not a big problem to take more than one or two thousand kilometers or extend the usage period by more than one and a half years. If the car is strong, it can be replaced in advance.

Generally speaking, the antifreeze replacement cycle is three years or 50,000 kilometers. You can adjust the replacement cycle according to your usual car use situation, or test the freezing point at the repair shop. If the freezing point is qualified, you can use it. However, the instrument can only measure the freezing point, and many owners ignore the boiling point. The long-term use of antifreeze will lower the boiling point. In summer, it can effectively prevent the engine from boiling and keep the engine working at normal temperature. The main indicator is the boiling point. The coolant is alkaline and its pH is generally between 7.5 and 11. If it is outside this range, it should be replaced in time.

There are also some experienced masters who have said that if you don't add water, you can use it for a few more years. If you don't have it, you can add it. You can still use it for six or seven years.

When it comes to antifreeze, it will be changed in two to three years. I believe many people will think that Xiaobian is advertising antifreeze. This kind of person is definitely not in a minority, because Xiaobian also saw many people saying when sorting materials. I have used it for six or seven years, and even ten years is no problem. Xiao Bian can only feel that there are too many gods. Xiao Bian just wants to remind everyone to pay attention to the replacement of antifreeze, because there are indeed many car owners who have not replaced the antifreeze in time, causing the water tank and cylinder to be corroded. Some owners have not changed the antifreeze in four or five years. When they are replaced, they smell a bit of burnt smell of the coolant. It is recommended that you check it in three years or so to avoid deterioration of the antifreeze and corrosion of the water tank or cylinder.

Well , the antifreeze replacement cycle will introduce you to everyone. It is recommended that those friends who have used their confidence for seven or eight years will also check it out and be careful.
