I just saw a really detailed radiator review from member @Irun who has used several different radiator types in his rebuilds. In his thread he mentioned liking Koyorad A2798 a lot, as well as the Koyorad A2102 and several others. In particular, the Koyorad brand sounded attractive to me…. It’s described as being reliable, quality built and what I interpreted as being as good as the discontinued OEM Mopar.
However, if you look at the dimensions of the 2 Koyorad radiators that were recommended they are significantly different….
The A2798 core is around 26” wide x 17” tall x 1” thick with plastic extending width wise another approximate 4”. Meanwhile, the A2102 core is around 19.5” wide x 18” tall x 1.3” thick with plastic extending on top and bottom adding another 3”. The A2102 also has what looks like a bracket (similar to what I currently have in my Jeep), that adds another 6”-7” total in width.
Inlet dimensions are fairly close with a 1/16” ID larger difference in the A2798 at 1-5/16”. Outlet dimensions are more varied with the A2798 being 3/16” smaller than the A2102 (1-1/2”), at 1-5/16” ID.
In my 2005 4.0L, the current radiator measures with the core at around 20.5” wide x 19” tall x 2” thick…. Plastic extends about another 2” in width, 4” total in height and another inch in thickness. It’s then positioned in a bracket that extends out 27” wide total with cutouts for headlamp nuts. Inlet ID looks around 1-1/4” and outlet ID at 1-1/2”. Hopefully these dimensions are close to other members’ Jeeps and I don’t have a “spotted zebra” under my hood….
Of the 2 radiators, the A2102 matches my existing radiator’s dimensions best and possibly others (?). Meanwhile, the A2798 would be a very tight squeeze width wise, but a very spacious radiator below leaving around 7-8” open space with probably just a little lost to re-stuff things that the greater width had forced to move out of the way. (???)
Of the 2 radiators, I was getting the sense that the A2798 was preferred over the A2102 for those very talented rebuild members.
My question is which one do members like best collectively and why? And if the A2798 is the preferred leader from experience and performance, are their tips on; 1) fitment - especially width wise, 2) what everyone is doing with the space below, 3) what fan shroud would you need, 4) what fan size/clutch would you need, and 5) what speciality bracket or hardware might be needed?
