If the water touches the block (and it does) and it touches the barbs (and it does), then there will be galvanic corrosion.
Water, distilled water, additives, it doesn't matter, it still happens, but at a slower speed with the additives.
Grounding strap, no strap, it makes no difference. It's as inescapable as oxygen in the air.

Ahh but water actiing as the electrolyte for this "battery effect" I would imagine speeds up the process quite a bit.......If it is no longer the "ground" between the two dissimilar metals such as aluminum rad and copper block would that not inhibit the effect to *some* degree?
