The first thing you need to do is fill the system and pressure test it for any leaks.

I mean fill the entire system to remove all air.

Okay so when I pop the hood, I noticed that the overflow was full and when I open the cap to the radiator, the fluid started coming out.

The car was not hot when I opened the radiator cap. The car had been sitting for at least a day.

There are no other ideas. You were advised to pressure test the system and you have not done that.

You can rent or purchase a pressure tester but it is becoming increasingly obvious that this diagnosis is likely beyond your abilities and you probably should bring it into a reputable shop for diagnosis.

start the car... let it run to hot. feel the motor to radiator , radiator hose. If its cold, put a new thermostat. if its hot do the pressure testing so you don't jerk a bunch of your time away chasing the rabbit down the hole

OK, stop posting nonsense and stop posting to old threads.
