Is the oil over the full mark? Coolant in the oil raises the level. It is near impossible to get coolant in the oil without also filling the coolant system with compression..
It is sometimes possible when the engine is NOT running.
Your description is a valid one for a small leak at the radiator or a hose or even the coolant pump itself..
