Hello i have been having some problems with a radiator that is blocked. i changed it and the thermostat at the same time. is there a spesial way to bleed out all the air ? because i cant get all the air out

. when i drive, it wont fill the top of the engine and it overheats. when i stop the car i hear and feel bubling in the hoses. And i only have the rapairmanual in german, and i cant read a damn thing of german :P. Sombody with an idea ?.
