How long can motor vehicle antifreeze be stored

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter. But to correct a misconception, antifreeze isn't just for winter, it's supposed to be used all year round.

But antifreeze doesn't last all the time, it also has an expiration date.

Generally speaking, the antifreeze used in most models will change due to volatilization, oxidation and other reasons, the freezing point and boiling point will also change, according to the instructions of most car companies for the use of antifreeze, the general replacement cycle is 6-80,000 kilometers, or about 2-3 years.

However, as antifreeze manufacturers continue to improve their formulations, their service life is also increasing.

It is worth noting the anti-corrosion and anti-rust properties of antifreeze. The metal parts that have been corroded for a long time will generate a large amount of rust, and the serious ones will gradually corrode through the metal plate and cause leakage, which is directly related to the service life of the automobile cooling system. In order to prevent excessive foaming, the thermal exchange between the antifreeze and the engine parts is reduced, and the product is confirmed to be within the expiration date when added, and the current long-lasting antifreeze can be valid for up to three years.

If suspended solids, sediment or deterioration or discoloration are found in the antifreeze, the system should be replaced and cleaned in time.

The above shelf life is two years, don't use it, if it's three years, it depends on whether you store it according to the requirements, it is recommended not to use it, because antifreeze is generally two years shelf life.

You can use your own home antifreeze. Antifreeze is a glycol product. The pH value is weakly alkaline. Antifreeze is cloudy. The pH value is less than or greater than 11 and should be replaced in time.

It's usually 5 years, but if you use it, you can only use it for 2 years!

It stands to reason that antifreeze can be used if it has been left for three years and has not exceeded the expiration date. Antifreeze that has passed its expiration date will deteriorate, produce impurities, and some internal chemical components may fail, which will have a certain degree of impact on the cooling system or engine, and cannot be used. Also, antifreeze does not extend the shelf life because it is unopened.

Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers, of course, this is only a reference cycle, because the driving situation of each vehicle is different, it is necessary to choose to replace it according to the actual use, check the use of antifreeze, and if it is found that the antifreeze is insufficient, replenish it in time.

If the antifreeze is insufficient, you should pay attention when adding it yourself, do not add too much, not too little, add it to the highest water level and the lowest water level scale, do not use tap water to use antifreeze, because the freezing point of water is low, and the water contains impurities, which is easy to form scale, which will cause blockage; Different brands and models of antifreeze may have different formulation ingredients, and if they are mixed, a variety of chemical components may react with each other, which will affect the effectiveness of the antifreeze.

The shelf life of antifreeze is generally about two years, which obviously has exceeded the shelf life, if you want to continue to use it, you can go to the store to test the freezing point and pH of antifreeze when you use it, if you meet the standards, it can also be used.

Hello Antifreeze can be used if it has been left for three years if it has not exceeded the expiration date, and it cannot be used if it has exceeded the expiration date. Antifreeze that has passed its shelf life can deteriorate, produce impurities, and some of the internal chemical components may fail, which can have some impact on the cooling system or engine.

It's no longer available.

1.Antifreeze has a shelf life, generally two years, 2At present, the antifreeze is an aqueous solution of ethylene glycol, and the concentration ratio of ethylene glycol is about 30%-60%, if it is in the Northeast, the concentration of ethylene glycol in the antifreeze can only reach 70%, and the freezing point at this time is -68 degrees Celsius.

It is usable normally, and the antifreeze seems to have a shelf life of five years.

It is usable, and there is not the opening of the word.

The shelf life of antifreeze is usually two years (some products will be longer), and you should confirm that the product is within the expiration date when adding it. Long-lasting antifreeze with a validity period of up to three years.

For those vehicles that run for a long time, such as taxis, etc. Generally, high-quality antifreeze is replaced every year, and wheel sheds can be replaced every two years or every 30,000 kilometers for those vehicles with short operating hours.

In order to prevent excessive foaming, the thermal exchangeability of the antifreeze with the engine parts is reduced, and the product is confirmed to be within the expiration date when added, and the long-lasting antifreeze can be used for up to three years. If it is found that the antifreeze is slippery, the suspended solids, sediment or deterioration and discoloration should be replaced and cleaned in time.

Some car owners feel that the materials in the 4S store are too expensive, so they find ** or buy them online. Mr. Wang said that he accidentally forgot the antifreeze he bought 5 years ago, can he still use it in this situation? What is the shelf life of antifreeze?

Synopsis

Antifreeze, also known as antifreeze coolant, is a kind of coolant containing special additives, which has the functions of antifreeze in winter, boiling in summer, waterproof, anti-corrosion, etc., and is an indispensable liquid for automobiles. Therefore, the idea that antifreeze works only in winter is very narrow.

Can antifreeze be stored for 5 years?

The general shelf life of antifreeze is two years; Long-lasting antifreeze has a longer shelf life, which can reach three to five years, see the expiration date on the package for details. Some are not car owners who love the heart of the car and cut it, or the kind of car that is blindly excited as a cow, and the shelf life has passed and it is still used after a period of time. As long as the antifreeze itself has not deteriorated, there is no problem with use, and if you are not at ease, you can hand it over to the mechanic to check the quality.

When filling antifreeze, in addition to paying attention to the shelf life of antifreeze, we should also look at the boiling point and freezing point of antifreeze, the boiling point of high-quality antifreeze is about 110 °C, and the freezing point is below -25 °C, which is also the main reason why antifreeze has antifreeze and anti-boiling effect.

<> "In the case of a good storage environment, the antifreeze will generally expire after 6 months of storage after opening, and the shelf life of the unopened antifreeze is three years.

Precautions for using antifreeze are as follows:

If you want to change the antifreeze, you need to be careful not to add antifreeze during the hot drive. If the lid of the water tank is opened under the high temperature of the sky, it will cause the internal pressure to spray the antifreeze out, resulting in burns due to lead loss.

For different models and brands of antifreeze, it is not possible to mix and add, because the formula ingredients will be different depending on the brand and model of antifreeze, and there may be a chemical reaction after mixing together, resulting in poor performance of antifreeze.

Antifreeze cannot be directly replaced with water, nor can water be added to antifreeze. After all, the freezing point of water is low, and there are many anions and cations, and it is easy to appear scale and cause blockage after long-term use.
