I have a MY2006 911 Carrera with 61,000 miles on it.
The coolant is some shade of red/orange/pink so I guess that means that at some point it has been flushed with the newer version? (no records on that work)
The temperature is always sitting steady at 175, regardless of driving conditions.

Here is the issue:
The coolant level always sits at about 1 inch below the minimum line of the reservoir. Even after filling it up to between min-max level it will drop to the same level once the engine heats up again.
It will never drop below the same 1-inch-below-minimum-level so it is not loosing more than that initial small amount. While the engine is warm when opening the radiator cap, the level slowly rises up to the minimum level.

I did put a brand new Porsche reservoir cap on it yesterday since I thought it might not regulate the pressure properly but no change.

This does not seem normal although since the level remains constant once it dropped to 1 inch below the mark I assume this is not really critical, right?
