Hi, my name is XXXXX XXXXX the engine fully warm, it should run about 200, it will go up and down, the coolant fan does not cme on until 220 degrees, so it can run as high as 220, then the fan will come on and wont shut off until 210, so normal cruising it should be at about 210, but can go higher at an idle,Tim
