I have been having over heating problems with my Avanti. Where I am getting confused is my temperature gauge will show between 190 and 240 will vary no matter if I am going slow or on the highway. I will open my hood on the car take my temperature sensor gun and point it where the sensor is located and get a reading of 170 degrees. My temperature seems to drop every time i open the hood on my car.
The question I have is should I rely on my temperature reading tool as to being accurate? Should I point to a different part of the engine instead of the back the head where the sensor is located?
