The 2012 Hyundai vehicle is likely to require blue antifreeze, which is a hybrid organic acid technology (HOAT) coolant. This type of antifreeze is typically blue or green in color and is designed for use in vehicles with aluminum components.
Mixing HOAT antifreeze with conventional green antifreeze (inorganic acid technology, or IAT) can cause the formation of harmful deposits and corrosion in the cooling system.
Mixing HOAT antifreeze with Dexcool orange antifreeze (extended life coolant, or OAT) can also lead to compatibility issues, as these types of antifreeze have different additive packages.
To ensure the proper functioning and longevity of the cooling system, it is best to stick with the recommended blue HOAT antifreeze for the 2012 Hyundai vehicle.
