You cannot compare a V8 gas engine to a 3L diesel just by saying "same same," nor can you compare a daily driver with a car designed to drag race.

I guess I'm not be clear. I didn't say both engines were the same. My point was that they both create a lot of heat even thought they are different. The size of the Mercedes thermostat really doesn't matter because it doesn't open enough where its located because it gets hit with cold water and closes. The chevy thermostat gets hit with a more consistent water temp so it doesn't open and close as much. If they made an inline Thermostat that used the bigger Mercedes T-Stat then I would have used that. The location of the T-Stat makes more of a difference than the size.
