It first began when the radiator reservoir was leaking and cracked at the bottom. I changed that reservoir and also my thermostat. Since that time, when i'm driving, my radiator gurgles like its really hot and spills out of the top of the reservoir where the cap is. No warning lights are on and the car temperature doesn't read hot or overheating while driving. It occurs all the time when i'm driving

Hello,

You might have air trapped in the cooling system. That why it is gurgling when the engine is not overheating.
When the engine is cold, take the cap off the reservoir.
Start the engine, as you see the coolant go down on the reservoirs slowly add coolant.
Squeeze the radiator hose to purge out any air and add coolant as necessary.
When you can no longer need to add coolant, put the cap back on.
Also you might want to test the reservoirs cap as it is pressurized.
