The official MB coolant and/or Zerex G-05 alternative leave a white trail of dried white residue wherever they leak. Don't know if it's done on purpose, but helps tremendously in finding leaks. Perhaps it's time to take a look around with a good light.

make sure that the hose from nipple at top of radiator is going to the correct port on the bottle and not to the overflow connection right below the radiator cap.i have seen this mistake made several times.

Good point. However, I'm not losing any coolant. Ironically, I do have to add a bit to the other car from time to time. But not this one.
