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!
