Anybody have any write ups or advice on replacing a 2001 4.7 radiator?

I have done a bunch of reading but im not sure do i need to remove the bumper when you replace the radiator?

Is usaradiator.com a good store? Reputable, reliable fast shipping etc and they're products do work?
Also the upper radiator hose for the 4.7 is one piece right? Cap and all? The other size engines have two hoses for the upper on there site.

Im using these two links basically to do my radiator replacement, ones the chilton manual https://elibrary.mel.org/validate?ur...ch%3Fdb%3DCHLL (where you put in your a1234567891012 for you drivers license) and http://www.mobiloil.com/USA-English/...ator.aspx?pg=1 which is more of a generic car radiator replacement.

Any thoughts, suggestion, ideas, help would be great!
Thanks!
