Hello and welcome to JustAnswer!

If the coolant level is dropping then you either have an internal or external coolant leak. The leak could be the radiator, hoses, heater core, or a number of places on the engine, or if the leak is internal then it could be a head, head gasket or block issue.

What should be done is properly fill and bleed the system and then pressure test it if you're unable to see a leak. If nothing is revealed then a block test can be done to try and help determine if there is an internal leak.
