Coolant
2C_Coolant
Check the condition and connections of all cooling system hoses and heater hoses. Replace any swollen or deteriorated hoses.
The coolant level should be filled between the MAX and the MIN marks on the side of the coolant reservoir when the parts in the motor compartment is cool.
If the coolant level is low, add enough distilled (deionized) water mixed with antifreeze to bring the level to the MAX mark. If frequent additions are required, have your vehicle inspected by an authorized retailer of Genesis Branded products for a cooling system inspection.

Check the coolant level when the motor compartment is cooled. Coolant level is influenced by temperature, and if the coolant reservoir cap is removed when coolant temperature is high, hot coolant and steam may blow out under pressure causing serious injury.
-
Make sure the coolant cap is properly closed after refilling coolant. Otherwise, the motor compartment may be overheated while driving.
Check if the coolant cap label is straight in front and the tiny protrusions inside the coolant cap are securely interlocked.

Recommended coolant
-
When adding coolant, use only deionized water, distilled water, or soft water for your vehicle and never mix hard water in the coolant filled at the factory.
-
An incorrect coolant mixture may result in severe malfunction or damage.
-
Do not use alcohol or methanol coolant or mix them with the specified coolant.
-
Do not use a solution that contains more than 60 % antifreeze or less than 35 % antifreeze, which could reduce the effectiveness of the solution.
For mixing percentage, refer to the following table:

If in doubt about the mix ratio, a 50 % water and 50 % antifreeze mix is the easiest to mix together as it will be the same quantity of each. It is suitable to use for most temperature ranges of -31 °F (-35 °C) and higher.
Have the coolant changed by an authorized retailer of Genesis Branded products according to the maintenance schedule at the beginning of this chapter.
Do not use coolant or antifreeze in the washer fluid reservoir.
Coolant can severely obscure visibility when sprayed on the windshield and may cause loss of vehicle control resulting in an accident.
Coolant may also cause damage to paint and body trim.
To prevent damage to motor parts, put a thick towel around the coolant reservoir cap before refilling the coolant to prevent the coolant from overflowing into motor parts.
