The aurora's are self bleeding check the small hose going the top of your coolant bottle and see if you have coolant flow. If you do not there is a blockage there. You can try to use compressed air to clear this work well for me. You should see air bubbling in bottle when clear. When clear fill start engine bring temp up so stat open then fill as needed then put cap on let idle for a few minutes then let cool. Check coolant level after an hour add if needed

Feel of the top hose, if it's soft when the car is running and at operating temperature then it's probably air in the system, not allowing the pump to pick up the antifreeze. To get the air out let the car cool completely (like overnight) then fill the reservoir, leave the cap off and run the car until it comes up to normal operating temp. (watch to see you keep enough antifreeze so the tank doesn't go empty.
My 97 Aurora did the same thing and this fixed it.
