Engine Cooling problem
2000 Cadillac Deville 6 cyl Two Wheel Drive Automatic 90,000 miles
My car overheated along the highway. I broght it to the mecanic and after checking out the radiator, thermostat, and water pump he said it was the head gasket. I looked on line and none of the common observations re a head gasket were present e.G. White exhaust or the other usual signs. Another mecahic asked if they did a test for Co2 and that if I caould not get the car to him I could buy some type of tester that would measure if there was carbon dioxide in the radiator. Do you know what this is called. I went to a few auto supply companies and they didn't have it. I have read that you do not recommend sealants but a few people have used it with success?
What else are my options. A repair of the gasket is between $2,000 to $3,000 and to drop another used northstar engine in may also be problematic.
