Hi,

In non air-con car it is more likely to be the heater control valve. And as you have found out they don't cost much to replace so it would be a no-brainer to change it anyway..

It is more likely to start leaking or seeping on a drive so on tick-over for x hours will likely tell you very little..

Heater core can and will flood both sides as the coolant is leaking from behind the air distribution box so can, from there, go anywhere..
