Having problems with your 2006 Chrysler 300 ?
I have a 2006 chrysler 300 it will not reach operating temperature. It warms up while idleing like normal, but once I start driving on the highway the temperature goes back down. This happens when the outside temperature is below 45 degrees. I have had the thermostat replaced and I still have the same problem. This also causes my heater to blow cool air
