the fact that a radiator starts leaking 2 years after it was installed can be many factors.
Yep. I have a Ford van that was eating radiators for a while. Turned out the mounting points were tweaked by a deer hit, and every new radiator was installed with torque across it. Add some vibration and... a year or two later the tank seams gave up the battle and separated. The cure was to mount the radiator on some pipe insulation so that it is basically 'floating' on the bolts. This removed the torque on the body of the radiator. (As long as the bolts weren't cranked down to the max!)
Electrolysis can eat radiators, too, and a copper radiator will die from it just as easily as aluminum.
