The Ford Focus ST typically requires about 1.5 to 1.6 gallons (approximately 6 to 7 liters) of coolant when performing a complete system fill. It's important to use a coolant that meets the specifications outlined in the owner's manual, usually a 50/50 mix of antifreeze and distilled water. Always check the vehicle's manual for specific recommendations and ensure the system is properly bled of air after refilling.
