temperature or thermostat

  1. 1.6T spark engine temperature/thermostat

    Alfa 147, 156 & GT
    Ok so I bought a 147 driving up the road and the temperature gauge is jumping, I think it's possible the thermostat has been removed.... The car is sitting at about 70c but is moving down between that and 50c, then back up to 90c. Is there an optimum temperature or is this expected? Fruity...
