      I have a 08 Suzuki SX4. Whenever I’m driving over 70 mph the temp gauge slowly drops. The faster I drive the more it drops. It worse j. The winter than the summer. I’ve changed the thermostat, flushed and changed coolant, and replaced the temp sending unit. I’m out of ideas. What could the problem be. Thanks.

        I would check the wiring, connections and gauge.
        Also depending how it is setup the ECU.
        You might try installing a mechanical temp gauge to see what the actual coolant temp is.
