I have been noticing that ever since I replaced my original thermostat, my engine has been running hotter. If I remember correctly, the original ran around 185 F. My engine is now running around 195-205. The temperature specs aren't listed that I can find.

My original clearly had an AMG logo on the housing and has part number 1132030375.
The replacement (based on my year/make/model from FCP Euro) is part number 1122030275.

The original still seems to be available, but is 2.5x the cost. Does anyone have the temperature specs?
