To change the engine coolant on a 2003 Chevrolet Malibu with a 3.1-liter engine, start by ensuring the engine is cool. Locate the radiator drain plug at the bottom of the radiator and place a container underneath to catch the old coolant. Remove the drain plug and allow the coolant to completely drain out. After replacing the drain plug, fill the radiator with a 50/50 mixture of new coolant and distilled water, then run the engine with the heater on to circulate the coolant and ensure there are no air pockets. Finally, check the coolant level and add more if necessary.
