How do you change the antifreeze in a 2005 forenza?

To change the antifreeze in a 2005 Suzuki Forenza, start by ensuring the engine is cool and then locate the radiator drain plug at the bottom of the radiator. Open the drain plug to let the old coolant flow out into a container. After draining, close the plug, refill the radiator with a 50/50 mix of antifreeze and distilled water, and bleed the system to remove any air pockets. Finally, check the overflow reservoir and top it off as needed.
