My coolant lvl does go down, plus it leaves a semi permanent trail on the pavement from the chemicals of the coolant. There was one time where the coolant was pourring all over the ground and lost half my coolant.(This only happened once last 10,000 miles) Took it to the ford dealership, they did a pressure test and couldn't find anything wrong with it. I know for a fact that it is coolant. IF it was just water it wouldn't leave streak marks on the pavements that lasts for months afterwards. My only guess is that something is building up more pressure than the system can handle or some tubing is leaking with the heating and cooling of the day
