Bad radiator cap? It get hot and pushes coolant to the overflow reservoir, but the little valve in the cap is not working right. It's not opening up when it cools down and pulling the coolant back into the radiator.
Or, the rubber hose from the cap to the reservoir is bad. Somewhat same problem, it pushes coolant to the reservoir when hot, but when cooled down the hose allows air to be pulled in rather than coolant from the resevoir.
Or, it there is a leak in any of the hoses - radiator or heater - the same thing happens. When the coolant cools down, air is pulled into the system rather than coolant being pulled back from the reservior.
In general, the cooling system has to be air tight everywhere or there will be problems.
