What we are both missing is that the Hyundai manual recommends what type of coolant to use in two different places, and the two don't quite agree!
Let's move on... Look for a coolant that is EG and makes some mention of phosphate but no alcohol, you may have to peek at the MSDS for a particular product; color is of no concern. I kind of doubt you will find any coolant for sale these days that isn't compatible with aluminum, since aluminum has been used in cooling systems for over 60 years (that I know of), there are no mysteries. I use a Prestone "universal" coolant that is compatible with all makes/models/colors.
