What happens if you leave your radiator cap loose?
A loose radiator cap will cause the system not to pressurize, resulting in overheating. In this case, the coolant is more likely to be lost to boiling off than by simple evaporation. Depending on the vehicle, it may or may not have the ability to give codes.

What should I do if my car is losing coolant?
Engine overheating and coolant are closely related to each other. Loss of the liquid can lead to the overheated condition but overheating can also contribute to the coolant loss. Just fill up the tank to the maximum limit and keep an eye on the engine condition and the rate of coolant usage.
