The maker of the 2013 Hyundai Santa Fe Sport suggests using a Blue Extended Long Life coolant specifically designed for Asian vehicles with a Phosphate Organic Acid Technology. This coolant helps prevent rust build-up in the cooling system and lowers the freezing point, rather than directly cooling the engine. The coolant formulation varies due to the different metals used in the engine blocks, requiring specific additives to prevent rust. It's advised to flush the coolant system every three to five years, or every 30,000 miles, to remove rust and debris and maintain efficient engine cooling.
The 2013 Hyundai Santa Fe Sport utilizes a 50/50 mixture of dex-cool antifreeze and coolant for its cooling system.
