I have a strange situation happening on cold days especially. While driving at a steady speed like on the highway, the engine coolant temperature begins to drop as indicated by the gauge on the instrument cluster. As I understand, when the engine is at normal operating temperature, the gauge needle should be pointing straight up to 90 (C), right?
I immediately thought I might have a bad thermostat, or a bad sensor somewhere, or could be a bad gauge!!
Any thoughts, ideas, suggestions?
