Maybe they changed their ways or you got lucky. When I bought from radiator.com, they told me that I would get an OEM-quality radiator. Instead, they shipped me a piece of junk. It was thin, flimsy, and not even fully painted. It didn't even have a drain cock! I complained, and they swapped it for a different brand which seemed to be good quality. But it started leaking after a few months and eventually a column of fins simply fell out of it!



Well, that is my experience with them. It had to be 3 years or so ago. Maybe they have improved. I actually still run that radiator in one of my rigs. The leak plugged itself and it still cools fine.
