I am running a 160 degree thermostat. I bought a 180 tested both and the 160 (older unit) worked the 180 (new unit) failed to open. I am sure I have all air from the system. I thought that the outside temp would have some effect on temp. I do not have a heater in the car. The car use to run at 190 - 200 during the summer until I made some changes. Such as adding an expansion tank, stainless flexible hoses. I appreciate everyone's input!
