Copper Block, Aluminum Radiator, How much trouble am I in.

[Sketch]

I have the above stated combination in my system for 6+ months using water and Red line water wetter and see no problems. But someone told me that I was getting the battery effect and that it would eat itself to peices. So I took it all apart and see no damage other than normal oxiadation. And the water wetter says it provents the battery effect. So am i safe. Or do I need to spring $50 for a copper radiator? Any help would be great!

no, you'll be fine. The water wetter will have done the job.

I've covered this befor. What you're talking about is called cathodic erosion. And since you have two dis-simmilar metals emersed in an elctrolite theoreticly you could get pitting. In real life as long as you're useing some kind of anti-freeze you shouldn't have any prob. If you are really worried you could just throw a small chunk of zinc (sacrificial anode) in your storage tank.
