You want to do the following on a cold engine.
Remove the radiator cap.
Open the air relief screw and be careful not to loose the copper sealing washer.
Slowly add anti freeze to the radiator until coolant comes out of the air relief screw hole.
Once coolant comes from the hole stop adding coolant and replace the screw and sealing washer.
Top off the radiator and screw the cap back on.
Top off the overflow tank to the cold fill line.
Air relief screw location.
