The temp hand is fluctuating while driving down the road. Just replaced the radiator a few months ago. Thinking about replacing the thermostat to see if that could be the problem. No smoke or fluid mixing. Water levels are fine. A little dirty though. The mileage counter above the odometer isn't working right. It will register sometimes but will stick. The truck doesn't actually run hot. Could it just be the head unit causing the problem?
