Engine Cooling problem
2000 Cadillac Deville V8 Two Wheel Drive Automatic 186000 miles
I have a 2000 Cadillac Deville, It will run hot if I drive around 70 miles per hour for a period of time or if I run the air conditioner, I will have to turn the air off and turn the heat on until the engine get back to its normal temp. I have replaced the water pump and the Thermostat and there are no leaks, what could cause this?
