Can you tell me what type of coolant is used in the 2015 Hyundai Elantra?

The 2015 Hyundai Elantra comes with a special green extended-life antifreeze that uses OAT technology, specifically for Asian cars. To make sure you have the right ratio, blend it with water to create a 50/50 mix if it's not already diluted. You can locate the coolant reservoir under the hood, right in front of the engine within the fender wall area. Remember to only check coolant levels when the car has cooled down. Do not remove the coolant cap when the engine is hot or has been recently running to avoid splashing and potential burns from hot coolant. If you notice your engine running hotter than usual, warning lights coming on, or leaks at the front of your car, it could be a sign that your antifreeze levels are low. Additionally, if you need to replace or repair the thermostat, water pump, or radiator hoses, your antifreeze levels may have dropped.
