[V8] Coolant level, bringing it back to capacity

[jpb3]

Hi,

I just re-installed the radiator after completing the TB job.  My question
is how other listers have purged the air from the cooling system and filled
it back up to capacity?  I tried using a funnel on the inlet (top) but got
nowhere with that.  I don't think that just adding coolant to the reservoir
is going to do the trick is it?  Is there a good way to purge the system of
air and such?  TIA for any responses.
