2008 Honda Civic AT 1.8L (US) - Radiator Replacement Part#?
I'm on rockauto and other various sites and I see the Denso Radiator: DENSO2213233
https://www.rockauto.com/en/moreinfo...6EmZlQvfyk4%3D
Rockauto lists it as an MT radiator, which I believe is because it doesn't have an oil cooler. From anything I can see on the LX, there is no transmission cooler built into the existing radiator. Rockauto seems to have very specific vehicle variations for each radiator for this car. I guess my simple question is, will the mentioned radiator work, as dumb of a question as that is since it lists MT. The part numbers on a honda OEM site for this radiator are: 19010-RNB-A51 (US made) 19010-RNA-A51 (Japan Made) then for the manual you have: 19010-RNB-A01 and 19010-RNA-A01
It seems like the other rock auto ones either just list generic "sedan" or MT, but nothing really specific to AT. Anyways, any help in pinpointing which to use would be fantastic. I do like using Denso since it is an OEM manufacturer. I believe there is either a small leak in the radiator itself or potentially, more likely, just the o-ring at the quick connector on the bottom water line. It does seem that is where the coolant originating from (that area by the water line at the bottom). The hose itself isn't leaking.
Edit: It is a sedan
