i have a 99 pontiac grand am with a 3400 v-6 engine? i think and it overheats and boils all of my antifreeze. and i'm think about replacing the water pump and thermostat, maybe the heater core, the hoses are good/replaced, but i am also going to replace the radiator. i do pour in a gallons of premixed dexcool antifreeze almost everyday now. i can't find where the leak is going when i just let it run i'm stumped what could it be?!

Have the cooling system pressure tested. You may have a leak that started the problem but at this point you have probably blown a head gasket from overheating it.

There is no other option. Find your leak.
