change your thermostat, and your temperature sensor. The sensors can have a tiny crack in them and cause a lot of problems. Once this is done you should notice a difference. Special note, check to ake sure your fan is coming on, and that your water pump is good. Remember if you change your water pump, you must change your timing belt. If you don't you will be replacing them both in under 6 months. Also make sure your coolant is still good.

The next thing to do is to observe the car as it idles for 10 minutes to ensure the electric radiator fan is coming on if not replace the fan relay if that doesn't work replace the coolant temp. sensor that activates the relay that activates the fan after that ti can only be the fan itself that is if the fan is not coming on.

If you aren't getting an "Check Engine" code than I would say your gauge sensor has a grounding issue.
I would get the gauge sensor replaced just to be sure.

What you describe is quite normal. While the engine is running and the coolant is circulating the thermostat maintains the engine within its operating temperature range. When the engine is switched off there is still considerable heat within the engine and the coolant will continue to absorb this heat. With no coolant circulation, the coolant inside the engine will register a temperature rise to the extent your gauge measures. This temperature rise may persist for up to 15 minutes until the natural thermo-syphon of the cooling system starts to dissipate this heat build up and the engine starts to cool down. Because the cooling system is pressurised, the coolant is prevented from boiling off at this temperature above boiling point. Once the engine is restarted the coolant flow is re-established taking this excess heat from the engine and the system temperature returns to normal.
