Well' if the much better all Aluminum is not whats wanted, then my suggestion fwiw is get Denso being an OEM supplier & still part owned by Toyota the quality control standards are better do doubt there.
But' it appears Denso offers (2) Rad versions?
First is a cheapo, aka: "One Size Fits Most" (reviews reflect OEM cap fitment sometimes iffy, smaller fluid capacity stated on some even).
Part numbers generally begin with 221 on lower grade it seems?
Denso's best grade radiator is their Direct Drop in unit aka: "First Time Fit" models (OEM standard rads).
Most part numbers on these better rads start out with W1033 it seems? I bought a "First time fit" Denso for wifes Infiniti recently and it was spot on to OEM, I hit this post today so thought I'd respond.
If this info is already posted here I'm sorry folks, this thread is quite long to read in its entirety
, trying to understand if this is always the case myself idk, maybe it will help with future rads a bit
.
Places I started out verifying specs was PartsGeek & RockAuto but since things may change in future from what's posted online in threads Its probably best to look for detailed changes before simply ordering whats posted, one being Amazon parts finder. It is just horrible, many send backs happen there as we all know so do your homework before ordering anywhere online.
I'm not advertising to buy from above places it's just many places fail to list the needed info and imho Denso & other corps selling todays parts should really put a stop to their dealers laziness
. Being' the Denso website also fails in this category, I don't expect this anytime soon. Oh well' It just appears Denso offers two grades of rads in most cases so buy the better one if offered from my experience with W1033 and reviews read on 221?
Hope it helps someone?
Peace!
