okay so the thermostats on the 944s test water temp. we all kno that.

Now, with water wetter added to the coolant sytem, the water wetter changes the surface area of "hot spots" inside the cylinder head (making them smaller) to allow more heat to transfer to the coolant flowing through the system. Therefore, if a cooling system has water wetter in it, theoretically, the water temp gauge should rise a lot faster because the water is taking in more heat. Thus, the water temp will rise, but the engine temperature will stay relatively low.

So my question is, is will the water temp gauge rise a lot faster with water wetter, than without?

thanks
