Great radiator

Very good quality and easily replaced the OEM one. My only criticism is that it did not come with replacement mounting bolts.

Radiator replacement

It's been more than 3-4 years since I replaced my 2005 Dodge truck radiator from A1 so this should be the good review. First, I was impressed at the construction which was better than the original. There have been absolutely no concerns about the fit, cooling ability, and no sign of cracks or leaks of any kind. I definitely got my monies worth.

No leaks! Thanks!

If we bought the one with the filler neck and the one that was on it didn't have the filler neck is there a way to bypass it?

I am not sure, but my 2005 4.7L engine came with the filler neck on it. I think the bigger engine and newer years don't have the filler neck.
