How often should car antifreeze be changed?

In fact, different cars, for the replacement time and mileage of antifreeze is not the same, some cars can indeed be maintenance-free for life, because the antifreeze used when it leaves the factory is of better quality, so its antifreeze life can reach 200,000 kilometers, which is indeed maintenance-free for many ordinary family cars, because 200,000 kilometers are basically changed. But not all car antifreeze is of high quality. Generally speaking, the more expensive the car, the higher the quality of the antifreeze, the longer the replacement time, the cheaper the car, in order to save costs, the antifreeze used will be relatively poor, and the replacement time and mileage will be relatively short, so there is indeed no unified standard for how long to replace the antifreeze.

Although the replacement cycle of antifreeze is relatively long, however, there will be a reduction in the process of use, so pay attention to the liquid level when checking at ordinary times, if the liquid level in the residual liquid pot drops, then add a little antifreeze of the same color in time, or add some distilled water.

Car antifreeze is generally replaced every two years or every 40,000 kilometers, and the driving situation of each car is different, and the specific time can be decided according to the actual use. In daily car maintenance, it is necessary to regularly check the antifreeze to see if the antifreeze has decreased or deteriorated. ”

The cooling system of all cars is a sealed system, and in general, the consumption of antifreeze should be relatively small. Antifreeze, in most cases, will not be lacking, unless there is a leak in the cooling system. The antifreeze of the general model can be replaced once in 2 years or 40,000 kilometers.

The antifreeze replacement cycle of some luxury cars can be said to be 10 years or 200,000 kilometers. In fact, the replacement cycle of antifreeze car is relatively long, and car owners only need to replace the antifreeze in accordance with the user manual.

The replacement cycle of antifreeze is generally 2 years or 40,000 kilometers, of course, this is only a reference cycle, the specific replacement cycle should be decided according to the use status of the car, if the use of the car is stronger, it is recommended to replace the antifreeze in advance. If it is a new car, it is recommended to replace the original antifreeze when replacing, because the quality of the original antifreeze will be better, and there will generally be no boiling or freezing cracking in the process of use, and the service cycle will be relatively longer.

Of course, every car is different, you can check your car maintenance manual.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

The car antifreeze is changed every two years, because the validity period of the antifreeze is generally two years, and the expired antifreeze will cause corrosion of the cylinder block, and even cause serious damage to the engine. In addition, the freezing point of antifreeze is generally around -25, and if you go to a colder place, you need to change to an antifreeze with a lower freezing point.

When antifreeze is below the minimum mark, antifreeze needs to be added. When replacing, it is best to operate in a 4S shop or a professional repair shop, and when replenishing antifreeze, try to add the same product as the vehicle to avoid chemical reactions.

The refrigerant is generally replaced every 40,000 kilometers.

Ordinary coolant is generally replaced every 2 years or about 40,000 kilometers, of course, there is also waterless coolant, which can be maintenance-free. It never needs to be replaced.

The antifreeze of the new car is replaced every two years or forty thousand kilometers, time and .

Antifreeze is also called coolant, which means coolant with antifreeze function.

What it does is:

1. Maintain the basic stable temperature of the engine, prevent the engine from overcooling or overheating, and can also play the role of anti-rust and waterproof, and protect the radiator and cylinder;

2. If it is not replaced for a long time, it will deteriorate, the anti-rust function will be reduced, and a large amount of rust and dirt will be precipitated in the radiator, which will seriously lead to the puncture of the radiator pipe or the blockage of the core. So we recommend checking every six months and replacing it every 2 years or 40,000 km.

Two years or 60,000 kilometers.
