I have a FEH and during city driving, I have not seen anywhere near 190 degrees since getting my Scanguage 3.15* in November 2007. I also have a wind radiator block on top and plywood covering 70%(?) of the bottom grille opening.

The only time I can exceed 190 degrees radiator temperature via Scanguage would be during interstate highway driving with a long uphill. I have never exceed 202 degrees and this was after a three mile uphill journey. I recently completed a nearly 840 mile trip with the temperature ranging from 11 degrees F in the Am to 37 degrees F during the sunny PM without exceeding 194 degrees. Most of the time, the radiator temperature via Scanguage was in the 180's.
