I'd bypass the trans and engine oil coolers. No need to run them thru the radiator.

That's just it though, the radiator in my old 1/2 ton Blazer, without tow package, is the larger radiator. That's why I was making sure I wasn't missing something somewhere. ha
Obviously, 2 core > 1 core.
I was just making sure there weren't some ridiculous circumstances where like the second core was dedicated to the oil/trans and only ran halfway down or something... I just don't trust early 90's OEM Chevy design to be what it appears to be on the surface... I'm always suspicious there's a wrinkle in the plan somewhere. LOL

Thanks guys. I'll stick with the radiator that's in there now.
