Kia Sportage: Changing the coolant
WARNING - Radiator cap

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot coolant and steam may blow out under pressure causing serious injury.
Have the coolant changed by an authorized Kia dealer according to the Maintenance Schedule at the beginning of this section.
Put a thick cloth around the radiator cap before refilling the coolant in order to prevent the coolant from overflowing into engine parts such as the alternator.
