We have had experience of leaks on ally radiators. The problem was not electrolytic or overheating. The problem was due to the mounting of the radiator. If it is too rigidly mounted it can suffre from twisting as the car rides over bumps or takes a lot of vibrational input from road and engine. This process stresses the joints and will lead to failure either sooner or later. Mount the radiator on rubber mounts. The little rubber mounts with a thread at each end are ideal but choose one with a very soft rubber compound. Worked on my car after doing in two ally rads.
