Copper and nickel have almost the same anodic index, so galvanic corrosion should not happen outside of extreme conditions.

Copper and nickel don't corrode when mixed. Copper and aluminum do. That radiator is nickel plated probably. As far as i know nickel plated copper and aluminum can safely mix because the copper isn't exposed to the water.

Nickel can corrode aluminium too though.

Doesn't it do it really slowly though? I remember hearing somewhere that it doesn't corrode as much.
