Dodge Grand Caravan-it shows the temp gauge in the dash. Prior to replacing the thermostat, it was as high as it would go and one day I even stopped and pulled off several times to cool down on my way home to hopefully keep from doing any damage. Now, it'll idle/run in the medium range of the gauge, so the coolant is obviously passing through the system.
