Re: Draining & bleeding?

This procedure drains all coolant fluid out of engine and radiator parts.
Then where does one refill the engine block.
Refilling only the overfill reservoir only fills up the radiator, no.
Then the engine cavity is still filled with air till the thermostat opens.
Am I missing some piece of the puzzle here.
Have to get into the cooling system cause hydraulic pump threw up on lower
radiator hose. ($11.50 from PAP). Have to put on a new one cause the lower
aorta is swelling.
Pentosin and Autobahn coolant all the way. Too many damn swishy things
occupying my trunk space for my taste. But got's no choice . . .
Thanks for any insight.
