A fair bit will. Top it up and run it with the cap off squeeze all the pipes. Once it's up to running temp feel both pipes top and bottom of rad and make sure they are both hot to make sure the thermostat has opened. Give all pipes a final squeeze and top fluid to correct level and replace cap.

Basically it will come out til the level of the sensor. I.e any pipes above including the expansion tank.
