Even if the temparature gage is not accurate, I notice engine stink when I park in the garage, so I believe that the engine runs too hot.
It doesn't matter what you believe, until you actually measure the temp, you have no data on which to build any diagnosis. A non-contact IR thermometer will quickly and accurately tell you the tempo of the coolant at or near the thermostat housing.
Most Fords operate in the range of 195-210 F when equipped with a 190-195F thermostat. This is completely normal.
The low speed fans should kick in around 210F +/-5 followed by the high speed fans about 8-10 F higher. Failure of the low speed dropping resistor is a fairly common occurance that leads to a loss in the low speed function.
You can monitor the PCM's evaluation of the ECT with a proper OBD-II scan tool and can monitor the operation of the cooling fans.
