The riser gasket is also a good place to lose coolant into the raw water side of the system

Thanks for the tip, I forgot that the coolant side and the fresh water side mix at the riser, so the fresh water has a place to exit.
I like this color coded diagram by CP Performance:

Closed cooling has to have the air bleed off to get the entire closed system full of 50/50 mixed antifreeze. One should fill as the engine is running and as the thermostat opens you should see coolant movement in the radiator cap. There may also be a bleeder valve in line to bleed the air out of the system!

Well, was good for about 6-10 hours of running at perfect temp after I added coolant. Then, out of the blue, last weekend it puked a shitload of antifreeze out of the motor, but I don't know from where? See new thread.
