So just need to go with your taste and see, which radiator works better for you, all of them have great quality though. Spectra are inexpensive, but they seem to only last a couple years before failing again. This is not a hard replacement. Spectra radiators are built in China (not Japan) or Canada. I wonder if all aluminum stacked plate exchangers (including the OSC) would have this type of connection? Go for which ever is cheaper IMO as I would not be surprised they were made in the same Chinese factory now. However, the Spectra appears to have a more reliable transmission cooler construction. This design is a hybrid of the Denso built OEM design. Many Spectra Premium radiators (and their fuel tanks as well) are made in Canada, so the quality is definitely better than anything built off-shore. Are you comfortable drawing a conclusion at this point in terms of radiator rankings? What companies will you find on this best radiator brands list? Oct. 7, 2020. When you removed the fitting, were you able to peer inside and confirm stacked plates? I'm on my third spectra radiator in my Jeep. Spectra are inexpensive, but they seem to only last a couple years before failing again. True, the actual ATF pipe elbow attaches separately, but the exchanger connection, mechanically, is similar to the OEM design. Denso is a much better quality radiator. So, the dice was rolled and a trans port was removed from the new OSC rad - which uses a similar two stage assembly at the OTW exchanger. From my brief reading of the thread, my guess is the Denso radiator has better cooling/thermal transfer performance for both engine coolant and transmission fluid. Rockauto has two radiators: Spectra Premium CU2721 (https://www.rockauto.com/en/moreinfo.php?pk=539628&cc=1417216) or DENSO 2213305 (https://www.rockauto.com/en/moreinfo.php?pk=4722906&cc=1417216&jsn=370). They are all very close in price. Press question mark to learn the rest of the keyboard shortcuts. The thread is focused around the Strawberry Milkshake of Death (SMOD). The reasons I went with Spectra: 1) when I replaced the radiator in our previous vehicle, the first one I got had an undersized transmission cooler in it. If you plan to buy one just tell the seller to check the overflow nipple is intact and before shipping, ask him to add some additional packing around the nipple. Made in Canada. :(. The drop in fit feature also is popular with consumers as it makes installation an easy process. In other words, it's my guess that the OSC uses the same type of stacked plate exchanger that both the OEM and Koyo use -- with female threads and o-ring seal at that connection (in addition to the larger o-ring to seal the exchanger to the tank). I wish I can buy a Mishimoto Aluminum Radiator (https://www.mishimoto.com/automotive/aluminum-radiator-performance.html).

If anything, there's an additional connection (the second flare nut on each fitting) that might could be avoided by using a one-piece fitting like on the OEM radiator. Tail light and break light are the same on my vehicle but my tail light isn't working unless I break.
