Does antifreeze need to be replaced?

Automobile antifreeze needs to be replaced, because the shelf life of antifreeze is about 2 years, and the shelf life of better quality antifreeze can be as long as 5 years.

At the same time, antifreeze has a shelf life if it is not unsealed. If the antifreeze is stored for a long time, the chemical composition will fail. Therefore, if the vehicle antifreeze is not replaced regularly, it will have an impact on the cooling system or the engine.

It is recommended to replace antifreeze every 40,000 kilometers. When replacing antifreeze, you should choose the same brand and good quality antifreeze. When adding, you need to add it in the case of a static car.

At the same time, different brands of antifreeze should not be mixed, because different brands have different ingredients. If mixed together, it will produce a chemical reaction, which will affect the performance of antifreeze.

Anti-freezing function:

The full name of antifreeze should be antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from cracking the radiator and freezing the engine cylinder block or cover when parking in cold winter.
