My suggestion would be to rent a pressure gage tool at your auto part store. That way you can force coolant out of any little hole it is leaking from.
And there is no sign of a leak below the car? How much volume do you lose daily?
Look at the top of the intake manifold. If you see coolant there it's the intake manifold gaskets. Hope that helps! Jim
Check the small hoses around your thermostat, passenger side on top. The plastic fittings get hairline cracks and leak under pressure and coolants evaporates leaving no trace. Suffered this for years. Metal replacement parts are just a few dollars at Autozone and the hose push on and off
