How do you change antifreeze in 2006 Pontiac vibe?

To change the antifreeze in a 2006 Pontiac Vibe, start by ensuring the engine is cool and then remove the radiator cap. Place a drain pan under the radiator, open the drain valve, and allow the old antifreeze to completely drain out. Close the drain valve, then fill the radiator with a mixture of new antifreeze and water (typically a 50/50 ratio). Finally, run the engine until it reaches operating temperature, check for leaks, and top off the coolant as needed.
