How do you replace radiator on Hyundai Santa Fe?

To replace the radiator on a Hyundai Santa Fe, first, ensure the engine is cool and disconnect the battery. Drain the coolant, then remove the upper and lower radiator hoses, the transmission cooler lines (if applicable), and any mounting bolts securing the radiator. Carefully lift out the old radiator and install the new one in reverse order, reconnecting all hoses and lines, and refill the cooling system with new coolant before testing for leaks.
