I drove my car back from Oregon and the car started to overheat. I took a look at the water levels and everything looked ok, but I still needed to drive for another few hours and had no way home. Long story short right when I got home the engine started to smoke. I took a look under the hood and I know it's not the coolant expansion tank or a blown head gasket. It only has 35000 miles on it and I just can't seem to find the problem. Thanks for all your help!
