The small rubber hose from escape outlet on the radiator filler neck through overflow reservior cap have to be long enough to be submerged under the coolant to absorb the coolant back into the radiator.
Are you saying the converse to this is that the reservoir has to have enough liquid in it to keep the end of the hose submerged so that the system will work properly?
(I'm not challenging, just pointing out the need to check the reservoir level the same as you would check the oil.)
