You can get a head check done, this will check for any exhaust gasses in the cooling system, a sure sign of a head problem, but I would also recommend that the thermostat & radiator be inspected as well.

Today I removed the thermostat, and put put it back together without the thermostat to see if that was the problem, but still the same exact thing.
My radiator does not have anywhere to apply coolant to, you can only apply it to the expansion tank.
The correct coolant is the 50/50.
I drained it and added the 50/50.
I did realize that the CAP in the expansion tank is broken.
Its a Pressure Cap and the little spring thing is sideways and broken.
That might be the problem.
I will replace the cap tomarrow and try the same thing again.
This is the problem, I drive the car 10-15 minutes with the fans on and blowing the right direction, and everything is fine and smooth, the Temperature meter never passes the halfway mark.
But once I shut down the car, the coolant starts boiling and steaming in the expansion tank and it gushes all out of the tightly closed cap.
Now that I realized that the caps pressure thing is broken, hopefully that was the problem, but I'm skeptical it is.
