Well you can pressure test the coolant system and check for an internal leak.

You can also put dye in the coolant and then go and run the car hard and let it get up to temp then pull the plugs and check for the dye on the plugs. The is how the Ford dealership found the leak on our F-350 truck. It was using about 3 gallons a week and didnt have any cross contamination.
