I'm having a cooling system issue and I know the problem, the question I have is this, my car has two, factory coolant temperature gauges, one is an analog (I guess) needle gauge which reads C and H with normal running temperatthy. In the middle. I assume the value to be 120°f minimum and Max at 300° with center being normal operating temperature at 220°f. Then the digital LCD temperature display. I also have an OBD2 reader and a phone app called Torque which receives and displays all readouts from the cars computer etc. With the coolant temp gauge on it. All three working simultaneously give me 3 completely different temperatures each one about 12 - 15 degrees from each other the digital factory may read 206 and the factory needle will be in the middle or a little over, and the OBD2 will read 243 degrees. Now which do I trust to be the most accurate? I need to know because besides the obvious overheating problem, the car has aluminum heads and I can't be overheating those at all for obvious reasons. This is potentially catastrophic to my beautiful fast Hemi motor. So I ask again which gauge do I believe?
have the same problem?
