Because you have a coolant leak. Just because it's not running doesn't mean it can't leak.. the car not running just means that there isn't going to be heat to open up the thermostat. Coolant can still leak out. You can rent a pressure tester and adapter cap for that vehicle, pressurize the system, and locate the leak in order to fix it. You might have to replace a hose, or you might have to replace the radiator. Without being able to pressure test the system and see the leak for myself, I can't tell you which it's going to be.

How do you flush the radiator in a 1999 Pontiac Grand Prix?
The radiator on a 1999 Pontiac Grand Prix is flushed by draining the coolant, filling the system with water, adding a liquid flush to the system, and running it for a few minutes. The system is then drained, flushed with fresh water, and refilled with coolant.
Why would my1990 Pontiac fire-bird leak coolant while i pour it in radiator when its not running?
Because the cooling system is compromised somewhere, and that's allowing the coolant to leak out. The radiator could be punctured, a coolant line could be cut, a hose clamp could be loose or broken. Worst case scenario, the water jacket itself could be compromised.

Does water in the reservoir circulate through radiator when engine runs?
No. When the engine is running coolant is heated and expands. Excess coolant then flows from the radiator to the expansion (overflow) tank. When the engine is shut down coolant cools and contracts drawing fluid back out of the tank to keep the radiator topped off.
Why would a 1998 Pontiac Transport Montana over heat after the thermostat and coolant sensor has been changed?
You more than likely have a bad water pump. With the car running, open your radiator cap and see if the water is circulating through the radiator. If not, then your water pump is bad. Hope that helps...
Do you check the radiator liquid when the cars on?
NO! That would be dangerous. Cars' coolant systems are pressurized, so if you open the radiator cap while the engine is running, it will spray HOT radiator fluid (water mixed with ethylene glycol, usually) all over you, and sometimes drain the radiator of coolant.
