The gauge could be a bad thermostat or temp sensor. As far as the coolant, place a large piece of cardboard under the vehicle to see if anything is leaking. Also, pay attention to the exhaust of the vehicle. Watch for white smoke. Next, check the engine oil to make sure the coolant isn't mixing with the oil.
Let me know what you find.
