All the cars I swapped to green had aluminum radiators, so I can't offer anything on my own personal as far as a brass radiator. The 3.1 has iron block with aluminum heads as does the Vibe.

All I do know is that the green never ate any of the old radiators up, my 6.5 diesel has a brass radiator, and iron heads and block. Non original brass radiator has a ton of miles on it (truck has 270,000 on it) and has green in it also. I cleaned the system with white vinegar and then flushed it in 2017 before doing some traveling with it pulling my fifth wheel camper. I wanted to make sure the cooling system was working at optimum efficiency as 6.5 turbo diesels can heat up when pulling a load.

I used Carquest in all the vehicles mentioned, but I'm 99% sure someone else makes it for Carquest. I has to meet certain specs no matter who makes it, so a lot of it is private label, same as Carquest is.
