Did a drain and fill of my Genesis Coupe's coolant today using concentrate OEM Hyundai coolant from the dealership. This coolant was bright green in color, while the OEM coolant that came with the vehicle from factory was dark blue.
Does anyone know what the difference is between the OEM coolant and what the dealership supplies? The manufacturer recommended change interval is 5 years at first, then every 2 years after. Is this because the factory supplied coolant is actually a long life formulation, whereas the stuff you get at the dealer is just standard old school coolant?
