After I shut off my 2003 Cobra (with about 350 miles) it boiled over. When I shut it off the car did not seem that hot...maybe just a little over the middle of the gauge. The temperature was about 75 outside, but I had just parked it in the garage (out of the sun). Has anyone else had this problem? BTW I live in a higher altitude and cars tend to run hotter here, due to a lack of oxygen.
