Question:
I, too, encounter the same 3 degree F difference. On top of that, if I idle for over 30 min. my temperature reading changes into "5C." I’d spoken to my friendly service advisor at the dealership and he had no idea at all. Plus no documentation was able to unsolve the mystery….Anyone?

The sensor for the thermometer is in front of the radiator. On a hot day it will take a little time for the temp to register true. As far as accuracy, I wouldn’t trust bank signs any more than my car’s thermometer. It seems pretty accurate but a few degrees difference from a few bank signs seems like splitting hairs. If you really want to measure accuracy I suppose you could place a good quality recording thermometer in the grill and see how they compare. Just my $.02.

I have a 96 Explorer XLT 4×2 with the electronic compass & thermometer over the rearview mirror. I have read about callibrating the compass but can’t find anything about the thermometer. Mine reads 3 degrees higher then the actual temperature, based on all the theremometers I see on banks, advertising signs etc etc. Anyone else have this problem and how did you fix it? — Web: http://www1.linkonline.net/johnm/progeny.htm

I wouldn’t be too surprised if the Exp. thermometer does read high, since unlike some other vehicles, my Exp. thermom. seems to update the temperature at fixed time intervals regardless of distance traveled, speed, etc. Hence its thermometer could be to be significantly influenced by the heat of the engine compartment (and always tend to read somewhat high) except after several minutes driving at constant, moderate speeds (at least 20 mph?). On the other hand, my Probe’s system requires such an unreasonable combination of distance/speed driven before the thermometer will update the temperature, that it never happens! I can ride around town *all day long* and never see anything other than the same temperature it recorded in the morning when started. A real joke! I don’t know if there’s a way to calibrate the Exp. thermometer, but you may find it actually is fairly accurate except for the stop-and-go driving conditions. At least you get a reading within 3 degrees of actual. It could be worse ;^) Phil Rose
