Under normal circumstances it will have some pressure just less than the bottom hose. The bottom hose is directly pressurized by the water pump while the upper hose acts as a return hose to keep the water flowing through the engine block. If there is no pressure you could be low on radiator fluid (water/anti freeze mixed) or have a thermostat stuck open.
