Many aftermarket aluminum radiators are not fully welded. That is to say that the tanks are expoxied to the core and not welded. These units have the highest rate of failure in my experience. Then there are all the fully welded aluminum units that do not fit correctly in the stock cradles, despite being advertised as direct bolt-ins. The poor fit causes stress and movement that eventually fatigues and cracks the aluminum at some weak point.

With that said, I have had very good fit, performance, and longevity from my two-row, cross-flow, fully welded aluminum radiator from BeCool. It was a bit more expensive than many others out there, but it has served me well.
