hi Paul,
To be perfectly honest, that Air-Lock system has no bearing on water blowing out. It only comes into operation when the cap is removed. This locks off air/expansion space in the header tank, so that you cannot put too much water in the radiator, thus weakening the anti-freeze, and also if overfilled it would blow out. So, providing you have enough water to cover the top hose fitment, then I would say you should be good to go and see how it behaves. You will find with a lot of these non-pressurised systems that if you put too much water in, there will be an initial blow out of water, then it will settle down, it is knowing to what point you fill to.

regards, Richard
