Fluctating engine temperature at constant speed S40-V40 2002

If the 2002 is similar to the 2000 S40 there is a temperature sensor screwed into the thermoatat housing. Since the temperature is fluctuating so quickly on the gauge it might be the connection on the sensor or the sensor itself.

Look to see if there is a connector in the tstat housing and go from there.

Also since youre there, changing the tstat probably wouldn't be a bad idea either.
