How to Replace Car Antifreeze?

[VivianMarie]

The method for replacing car antifreeze is as follows: Allow the engine to cool completely, then loosen the drain valve to release the old antifreeze from the bottom of the radiator, and add the newly diluted antifreeze. The functions of antifreeze include: providing anti-corrosion protection for cooling system components, preventing scale buildup to avoid reducing the radiator's cooling efficiency, and ensuring the engine operates within the normal temperature range. It is recommended to replace the antifreeze every 2 years or 40,000 kilometers. This replacement interval is only a reference, as driving conditions vary for each vehicle. Owners can decide the replacement schedule based on actual usage and should regularly check the antifreeze's condition.
