Hyundai Azera: Engine coolant
The high-pressure cooling system has a reservoir filled with year-round antifreeze coolant. The reservoir is filled at the factory.
Check the antifreeze protection and coolant level at least once a year, at the beginning of the winter season, and before traveling to a colder climate.
WARNING - Cooling fan

Use caution when working near the blade of the cooling fan. The electric motor (cooling fan) is controlled by engine coolant temperature, refrigerant pressure and vehicle speed. It may sometimes operate even when the engine is not running. Your vehicle equipped with GDI, the electric motor (cooling fan) may operate until you disconnect the negative battery cable. Not heeding these warnings could result in serious injuries.
