If this is the norm, ther should already be a bleeder valve. Older BMW have one on top of the system.

all systems need to be bled after service.... first off drain radiator, jack up front of car, fill coolant slowly and then start car turn heater on low and let run until fan comes on and thermostat opens, the lower hose will be warm and upper hot and the fan will come on. then when the coolant drops, top it off. if its already filled some cars ahve a bleeder on thermostat housing, if not you can remove cap on radiator and run and turn heater on and letr run with cap off it should bleed air and give upper hose a few good squeezes to remove trapped air.

Unscrew the radiator cap and run the vehicle with it off until it hits operating temperature, dial pointing straight up. Fill it antifreeze/water if need be and put the cap back on.

Look for the bleeder valve and open it till you get a constant flow of coolant coming out then re tighten.
