I have replaced my radiator, fan, water pump and thermostate. My temperture gauge still rises above half way when I'm doing city driving. Sometimes when I travel alot in the city and turn the car off, I hear the water boiling in the resovoir. When the mechanic replaced my water pump and radiator he replaced the coolant with water and said I don't need coolant until the winter months. I saw the water in the radiator after the water pump was replaced and it looked very dirty and rusty. I didn't think it should look like that considering I just replaced the radiator. Also, my AC runs warm when I'm at a stand still, however, when I'm driving it is cold as it should be. I own a 2003 Chevy Impala LS 3.8 Liter Engine and I have approximately 130K miles.
