The hot side water out of the block to the top of the radiator is to make sure any trapped air is removed from the block and is in the top of the rad where it belongs. Thermostat should be at the highest point to be sure it’s not in an air pocket or it won’t work correctly.
The bottom of the cold side is there to insure you don’t suck air if the radiator is not completely full as in always primed.
That 1-2 liter of coolant won’t be in the tank for more than 10 seconds at 3000 rpm climbing a hill or shifting through the gears before it gets pushed through the core. It has absolutely no time to “cool and drop” before being recirculated.
Oil and trans heat exchangers in the tanks are usually near the mid or bottom because air will be at the top and coolant will always be at the bottom. It won’t work unless it’s submerged. Even with a half full radiator, at higher rpms the hot side tank will fill most of the way with most of the core flowing, the cold side will be really low....back at idle it will be about half way on both sides and core.
