I recommend that you get a cooling system diagram and start reviewing to become more familiar with the system. Then go to your local auto parts store and rent/borrow a coolant-system pressure tester. Basically you remove the radiator cap and install the tester and pressurize the coolant system. This will help you locate where you are loosing coolant. Possibilities could be loose hose clamp, defective hose, radiator cap, but hopefully not a head gasket. Start with the easy stuff first, if this doesn't locate it I would do a leak down test. Have you checked your oil for signs of coolant? Good luck .
