How often does antifreeze need to be changed?

During car maintenance, many friends ask me which parts must be inspected and which items must be done? In fact, what I want to say is that among auto parts, each one plays an extremely important role, and routine inspections must be carried out carefully. In the early years when my country’s automobile industry was underdeveloped, many parts had to be imported. But now most automobile parts are domestically produced, which also reduces a lot of costs for our daily maintenance.

Car antifreeze is one of the main additive fluids in the “heart” engine of the car. It is as important as engine oil. Its full name is antifreeze coolant. It is to prevent the engine cylinder block or cover from being damaged when the car is parked in cold winter. In daily maintenance, we often only pay attention to whether the engine oil needs to be replaced and how often it needs to be replaced, but rarely pay attention to whether the antifreeze needs to be replaced.

1. How often should car antifreeze be replaced?

Antifreeze has many functions. It is mainly used to keep the engine running in a healthy state, preventing the engine from boiling in the summer and freezing in the winter. , and it also has the advantages of being anti-scale and anti-rust. A friend of mine who is an auto mechanic told me that I must develop the habit of regularly changing antifreeze.

Professional auto repair people say that the recommended period of antifreeze replacement is 4 years or 50,000 kilometers. If it is a relatively expensive luxury car, it is recommended Antifreeze needs to be replaced once every three years. After all, antifreeze is not expensive and is not expensive compared to the engine of a luxury car, so frequent replacement is beneficial and harmless.

After adding antifreeze once, it is generally not recommended to use it for more than 4 years. Once it exceeds 4 years, the antifreeze will become invalid and the engine will lose its antifreeze, antiboiling and waterproof properties. If the scale is damaged, it will easily lead to engine damage. At this time, the gain outweighs the loss.

But if the 4S store often asks you to change the antifreeze, such as once every six months or once a year, you should be careful. This is usually because the 4S store wants to change the antifreeze. Charging is just a means of charging. There is not much need to change antifreeze frequently, so you must keep your eyes open and don’t be fooled by 4S stores.

2. In addition to antifreeze, what parts should we pay attention to in maintenance?

Generally speaking, a car needs a major maintenance after its mileage reaches 50,000 kilometers. Maintenance includes not only replacing antifreeze, but also the following parts. ：

1. Brake pads. Generally speaking, brake pads need to be replaced around 50,000 kilometers. Once the brake pads are seriously worn, they will affect the braking distance and even cause the braking distance to increase. Movement failure.

2. The “oil” of the whole car. The oil of the whole car includes not only antifreeze, but also engine oil, brake oil, transmission oil, etc. Once It must be replaced after reaching 50,000 kilometers. These oil products have a “shelf life”. Once the shelf life is exceeded, it will cause failure, which will not only shorten the service life of the car, but also cause safety hazards.

3. Car tires, as the only parts of the car that are in contact with the ground, car tires are also one of the parts that are most likely to wear. Generally speaking, the tires can be Replace the tires according to the tread wear. If you really don’t know when the tires need to be replaced, then a simple indicator is “50,000 kilometers.” Once the tires reach this mileage, it is recommended that you replace the tires as soon as possible.

3. Why don’t people in the industry recommend that car owners change their antifreeze on their own?

As for the issue of replacing antifreeze, there are many tutorials on the Internet, and antifreeze is also sold on some e-commerce platforms. Many friends will choose to buy it online by themselves. Antifreeze replacement. Although this method is cheaper and lower cost, some people in the automotive industry say that it is still not recommended for car owners to replace their car’s antifreeze. Why is this?

It is understood that the steps to replace antifreeze in a car are still relatively cumbersome and difficult to operate. When we watch the instructional video, it is relatively simple, but after actual operation, we find that it is not the case. In the end, it will cost more money and time to go to the auto repair shop to replace it.

In addition, there are certain risks in replacing car antifreeze. The formal process requires taking protective measures to ensure that you will not be burned when replacing antifreeze. However, there are some online information about car owners doing it themselves News about burns caused by replacing antifreeze often occurs. Therefore, it is not recommended that you replace the antifreeze yourself. Instead, go to a regular 4S store or auto repair shop to replace it. During the replacement, the regular auto repair shop will also help you. It can remove carbon deposits from the car, allow the engine to burn more fully, and reduce fuel consumption. This is something that ordinary car owners cannot do.

4. Summary:

After reading the introduction of car antifreeze, did you not realize that there is so much knowledge in a small car antifreeze? In fact, although antifreeze is just a small part of a car, its role cannot be underestimated. The same is true for any part of the car. While we travel on a daily basis, we must also master a certain amount of car maintenance knowledge and develop it. The habit of regular car maintenance can ensure safe and secure travel.
