I have a 2004 optima Ex 6 cylinder. When in traffiic the temp gage moves past the halfway mark and I put the car in N and reve the engine and the needle moves slowly back down. This does not happen if I have the A/C on, the temp gage stays like its supposed to. I have replaced the thermostat, and it was fine for about 150 miles, then started again with the gage moving when Im in traffic. does anyone know what the problem is?

thanks,

When you use the AC, one of the cooling fans will turn on with it. WHen it's off, the fans should come on after the engine reaches a certain temp. With the AC off, have you noticed if the fan is coming on?
