How many liters of antifreeze should be added to the Elantra?

[AubreyMarie]

The Elantra requires approximately 4L of antifreeze. To prevent excessive foam formation which could reduce the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding. Long-life antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration/discoloration are observed in the antifreeze, replace it promptly and flush the system. Antifreeze is a specialized coolant containing additives, primarily used in liquid-cooled engine cooling systems. It provides excellent performance characteristics including freeze protection in winter, boil-over prevention in summer, and year-round anti-scaling and anti-corrosion properties. When topping up, always use the same brand of antifreeze. Different brands may have varying production formulations, and mixing them could trigger chemical reactions between additives, rendering them ineffective.
