Can a car lose coolant, but no leaks?
It is a slow leaks about an overflow in 2 weeks and no dye marks. The leak may be happening from the bottom hose or radiator drain. It may be happening only when the car is hot when you drive and the coolant is under pressure. Try checking it when it is hot, under pressure and while the engine is running.

What causes a decrease in the coolant level with no heat?
If your car has a plastic coolant reservoir with a MIN and MAX line then the level will fluctuate up and down at different engine temperatures. That is why your car is not overheating. Or, you could have a very small leak.
Can a coolant pressure test show no leaks?
The coolant pressure test is obviously showing a coolant leak. The system should not lose pressure if there were no leaks. Since the leak is not external, it may be getting burned. Maybe the intake gaskets leaking again?

Can a car leak if there is no coolant in the engine?
Even if you have depleted coolant levels with no sign of leakage, you could still have an internal leak that isn’t detectable from the outside of your engine. Detecting a faint, sweet smell of antifreeze with no signs of a leak is also indicative of an internal leak.
How can you tell if your car coolant is low?
Anti-freeze is a sweet-smelling compound that is added with the coolant to stop the water in the radiator from freezing during cold seasons. So, if you suspect your cooling system is leaking, check if your engine is producing a sweet smell. A main sign to indicate low or no coolant in engine is the increasing temperature gauge.
