Check your anti-freeze level. But it is probably just a bad temp sensor, loose connection, or corroded wire.

If you loose the connection at the sensor and touch it just quickly to ground, the temp gauge should increase rapidly to hot. Note, just short test for a second or two!!!!!! If you want to test it more profesional, use a resistor of 68 Ohms = 75% gauge meter position ( boiling temp.).

The sensor is not really expensive, I think I had to pay 50 USD for the origin.
