Wait until your motor is cold and then remove the radiatior cap. Start the motor, after the thermosat opens you should be able to see the coolant circulating in the rad. You might lose some coolant into the overflow bottle, once the car "burps" the coolant leval in the rad will drop. Top is off with the right antifreeze/water mix. Shut it down, install the rad cap and you shold be good to go.
