F11 520d N47 - How to vent the cooling system?

Hi All,

The water pump needs replacing on my F11 520d. I have used the TIS to familirise myself with the procedure. I understand that there is no bleed screw on this model and therefore the lower coolant hose needs to be removed. The problem i am anticipating however is upon replacing the coolant, is there a method of venting air out of the system without using the suggested vacuum filling kit, which i do not have?

Many Thanks,
Dean.
