I ordered the radiator on Wednesday and got it the following Monday. The box was damaged but the part was not damaged. After I watched the video that 1A posted I changed the radiator out in about 2 hours. Watching the video probably saved half an hour. The radiator has been installed 10 days and so far so good.

Great price not great packaging
So far so good with the new radiator. When it arrived the box had a hole in it and one of the hose nipples was bent during shipping. I tapped it back straight and so far no leaks. The price is great, I just wish they would beef up their boxes.
