Frontera Sport (Niagra) 2.0i Petrol 1997 'R' - Frontera temperature gauge - Ukrover

Gauge is on cold always now when driving and will not go to normal only when stuck in traffic goes to three quarters hot then slowly back to cold. Plenty of coolant and no leaks,am i heading for trouble?

Sounds like a faulty thermostsat. Does the heater run cool too?
