You might trying checking the coolant level in both your coolant reservoir AND your radiator once the engine has reached normal operating temps and the thermostat is cycling.

Pop the cap on the reservoir first then use a rag when removing the radiator cap in case of hot coolant overflow. With the engine running and the thermostat open, the coolant level should be flowing just a little below the level of the radiator cap opening.
