What Hyundai & Kia specifies
Hyundai and Kia share one coolant code in coolant makers' literature, MS591-08. Hyundai Mobis describes the genuine Long Life Coolant pre-mix as silicate- and borate-free [2], and a 2026 Hyundai manual says to keep the antifreeze between 35% and 60%, mixed only with deionised, distilled or soft water [1]. A product listing MS591-08 is the closest aftermarket match.
