KOYO HH021687 All Aluminum Radiator Fits

I didn't see much on this site, but just to confirm, I installed the KOYO HH021687 all aluminum radiator intended for the Titan in my 2006 QX56. It eliminates the transmission "cooler" built into the radiator, so I plumbed in a trucool 4588 external cooler and installed it downstream of the OEM stand alone cooler that sits in front of the radiator.

The radiator dropped in with no fitment issues (was a bit snug going in). It's been a few months, so details are fuzzy, but it seems like a couple of the clips at the bottom had to be zip tied.

I also installed the same model in my 05 armada
tight fit, but all fell into place. I already had the Tranny internal bypass from years ago.
