Hey man,
So do you mean keep running the car with rad cap off untill the water is at operating temp? Would the coolant not go everywhere? Also, the bleed screw is the little plastic one next to the radiator, correct? How do you know that there is no more air in it, does water start coming out at that point?
Also, i was reading about radiator flush etc a while ago and I remember people saying something about turning the heater on etc when bleeding I cant remember for sure, does that have anything to do with it?
Cheers
A
