Coolant level when hot.

This is probably a DUH answer coming but that's OK. Just got done doing all my coolant hoses, expansion tank, heater pipe O rings, fuel filter, cam position sensor, crank position sensor, secondary thermostat (because the 25 yr old plastic broke getting hose off), intake gaskets, fuel pressure regulator and rotted vacuum line. To my great joy it started once the fuel pressurized. Now to bleed the system. I know the cold full mark but where should it be warm and burped? Higher or lower than the cold mark. I can't seem to find this anywhere.

My guess you can't find it because it's kind of irrelevant. It's meant to be checked when cold. So after bleeding, button it up and come check it the next morning. FWIW I've always needed to top up after the next 2-3 drives, and my strategy was always bleed it, button it up, check and top up the next morning, go for a highway drive but stay local, check again the next morning and top up, then return to DD duties.

of course the level will rise when its running, it will rise 2-3-4 inches depending how hot. Do not do anything stupid like run the car for long duration with the cap off, or something really stupid like remove the bleed screw when the car is hot.

When you initially fill to get the air out, you remove the bleeder fully, then fill at the expansion tank you can fill all the way to the top of the expansion to help fluid move to the high spots in the engine. Then when it doesn't take anymore, remove the excess.

Thanks. I've had a tiny leak for years that would allow air to get in. I'd add some and half burp it. Never did a proper bleed until recently after doing the heater core. I overfilled it then and don't want to do the same this time.
