Re: where should top of overflow be in relation to top of radiator???
Agree.
The overall system will be a "closed" system, in that it should push the coolant out of the rad into the bottle when it heats up, and then suck the fluid back out of the bottle when it cools down.
It has to have a full system to do this, allowing it to suck back in via capillary action (a vaccuum).
Has the vertical hose fallen off the bottle cap, or is it missing? Otherwise you just have a bottle to catch any overflow, rather than a "surge tank" system.
Try it again with the radiator full (cold), and full to the cold mark in the bottle. Make sure there are no holes/leaks in the transfer hose.
