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.

You need to find a new guy to work on your car coolant has more then one purpose then keeping your water from freezing. It raise the boiling temp to well over 200 degrees verus water which I think like 140 degrees. Also keeps rust scale etc down I would flush the cooling system and put coolant and water back in. Then see how it does also fire the guy that put water back in and said your ok without coolant till winter.
