My car does fine on temp. But then I turn on my ac and about 5 miles it's over heating. And I can turn off AC and temp goes back to normal. But if I don't it start bubbles in the over flow tank then runs out on the ground. Any ideas?just put in new thermostat. But fixing to change it again along with new radiator cap 2
