coolant leak 1998 firebird

[poprokz]

At first I thought it maybe a hose pop or sumthin, but then i saw that the radiator was cracked. so i replaced the radiator and thermostat but i'm still losing coolant. what's wrong and where is it going? because my gauge still reads like nothing to empty?

you have to pressure test the system to find the leak, also could be head gasket, did you check for water in the oil
