Does Antifreeze Have an Expiration Date?

[MacLillian]

Antifreeze does have an expiration date. Typically, the shelf life of antifreeze ranges from 2 to 5 years. If used for too long, some of its chemical components may degrade, which can adversely affect the cooling system or the engine. A change in the color of the antifreeze may indicate that it has expired and deteriorated, leading to the formation of impurities. In such cases, the antifreeze loses its original properties and may cause blockages. The primary function of antifreeze is to prevent the engine coolant from freezing in low winter temperatures. Acting as a medium for heat exchange in the cooling system, it absorbs heat generated by the engine, dissipates it through the radiator, and then circulates the cooled fluid back into the engine. This continuous cycle helps maintain optimal engine temperature by providing timely cooling.
