Jumping coolant gauge. Anyone had this issue?
I have this problem where the coolant temperature gauge is swinging wildly, even though the engine is not overheating. For the purposes of debugging, I have replaced the temperature sensor with a resistor, and as you can see on the video, it has no effect, so the issue is probably inside the instrument cluster. The ampmeter shows the current flowing through the "sensor". Has anyone had any experience with the insides of the coolant temperature gauge?
