Isx blowing coolant out overflow but not overheating.

I end up replacing the radiator as well as the fan motors with the relay because the fans wouldn't turn on. I ended up using a power probe straight to the old fan motors and only fan #2 worked. I end up putting it all together-bled all of the air out of the cooling system with an airlift evacuation tool-and this thing is still overheating!The coolant was being lost through the coolant overflow hose. I fought with this, stopping every 30-45 minutes and adding 1/4 to 1/2 gallon of water.
