How many gallons of antifreeze does a Ford Explorer require?

As an American, I'd rephrase and expand the information this way: The Ford Explorer has a capacity of up to 4 gallons of antifreeze. It is recommended to replace the engine coolant at either the 100,000-mile mark or after ten years. Over time, the engine coolant loses its ability to prevent corrosion and provide proper lubrication. If left unchecked, the coolant can lead to radiator corrosion, creating rust that can damage the radiator and engine. Warning signs that indicate the need for an immediate radiator flush include coolant leaking underneath the vehicle and unusual engine noises such as grinding. Other symptoms of a malfunctioning cooling system include the smell of antifreeze or the vehicle overheating too quickly. Be vigilant for these signs to avoid potential problems with your car's radiator and engine.
