2007 pontiac G6, 3.5 litre engine. My car overheats as I drive it, and the heater does not get warm. It is winter here about 36 degrees and it over heated after driving in less than 5 minutes. Sometimes if your on the hiway for a long stretch the heater will get warm but if you slow down it cools. Also noticed the fan seems to stay on a long time after you stop the engine. We replaced the thermostat, added coolant, and there doesnt seem to be any leaks, although I'm not sure the water is circulating. Any help on what might be wrong would be greatly appreciated
have the same problem?
