Just keep filling until you reach the line. Mix 50/50 solutions in a seperate container first before pouring it in. Don't try to mix the water and coolant in the radiator itself. This way you're sure that you have a constant 50/50 solution.

Thanks for answering the question Rahray, I do have MB coolant & was planning on a 60/40 mix as I have some Redline water wetter I was planning on using - damn hot here in the California semi-desert - thanks all!

i run a mix thats pretty much water. the coolant (zerex g02, not any other kind if its not MB) does not have the same cooling capacity as water. it does extend the temperatures by delaying the boiling and freezing points, but it doesnt add actual cooling capacity.
now that its summer mine is pretty much just water. in winter i add coolant to make sure my coolant doesnt freeze overnight. no chance of that in summer.

I am actually looking into the viability of running an ELC in mine, but that's risky business considering it's outside of the manufacturer specification. Perhaps equally risky, but for a different reason. These types of coolant are rated for 500k-750k miles and 8-10 years which is desirable to me (and likely most everyone else for obvious reasons).
