90 - 100 degrees celsius is not considered hot for these cars.
The stock thermostat on my 93 300E opens up at 92 degrees.
I wonder why everyone freaks out when the gauge hits 100 degrees.....

Suginami,
I am sure you are aware that the variety of metals involved in an engine expand and contract, although minutely, through different temperature ranges. There exists an "optimal temperature" at which these metal surfaces are of a specific size to operate within the tolerances for which they were designed. A swing of a few degrees is negligable. However, a change of 20C, 25% more the "normal" for my car, makes me pensive. Is there something I do not understand? I am by no means an expert and am on this board to learn...
