I wouldn't put tap water in the MB's cooling system but you can. Do some reading and you'll find that your radiator will be in much better condition a few years down the line if you use distilled water.

If you do use tap water, then make sure you flush and replace it every 1 to 1-1/2 years. Good af can 'handle' tap water's impurities for that long but then it breaks down and turns corrosive to the alum.

Why even use tap water to begin with?? Distilled water is cheap and it's a great "investment" for your radiator.
