I ask forgiveness for my impatience.....

Anyway the pump is overkill. I will get this one since it has 10m of head pressure and 8400 l/hour of flow !!!

Regarding the aluminium radiator....couldn't anticorrosives do the trick? I can get hold of various chemicals from a friend who works at a lab. I read that phosphates help a lot so I could try those.

It is very difficult to find copper radiators since they are heavy and serve no purpose on cars really (that aluminium can not serve as well and in a cheaper way)

My loop would consist of ek supreme - super pump (should be a univer) - and car radiator.

Isn't there anyway I can get aluminium and copper to work together?

thanks!
