Antifreeze and corrosion inhibitors — general information (Hyundai Elantra J1)

If the temperature is expected to drop below 0°C, some of the water must be drained and an appropriate amount of ethylene glycol antifreeze added to the cooling system. If antifreeze is not used, it is recommended to add a corrosion inhibitor to the cooling system in the proportion recommended by the manufacturer.

Any ethylene glycol based antifreeze can be used. Do not use alcohol-based antifreeze as it evaporates too much.



Most fluids with anti-corrosion additives can remain in the cooling system for up to two years, but it is recommended to measure the specific gravity of the fluid after 6 months and repeat these measurements every 3 months.

Below are the proportions for adding antifreeze and the freezing temperatures of these mixtures.

Caution: Do not use antifreeze in the windshield wiper washer fluid as it will damage the vehicle's paint.
