How do you change antifreeze on 2008 infinity G35?

To change the antifreeze on a 2008 Infiniti G35, start by ensuring the engine is cool, then remove the radiator cap. Locate the drain plug at the bottom of the radiator and drain the old coolant into a container. After draining, close the plug and refill the radiator with a 50/50 mix of antifreeze and distilled water. Finally, run the engine with the heater on for a few minutes to circulate the new coolant, and check for leaks before replacing the radiator cap.
