If anything the rich cylinder would be cooler, but spend all your time with your infrared gun at the thermostat cover. That will be the only consistent temp area on the motor. As the thermostat opens and closes you will see the temp change, but if all is working properly it should be pretty close on numbers. Looking around on the engine you can find all kind of hot spots. Some areas of the motor don’t even get any water or have no water jacket around them. A lot of guys like to shoot the base of the spark plugs and that will be one of the hottest parts of the engine. Good for finding out if engine is running on both cylinders, but not so good for over heat diagnosis. Just my opinion of what we see with the motors that have sensors with errant warnings.
