Does a V-6 rad hold more coolent than my 4Cyl rad looks like it would be an easy swap if the extra capacity is there I think the hoses are in the same place

 

thats a good question.

i wonder if thats a practical mod???

bump

 

I think they are the same size...

 

I know with my '91 4Runner (3.0) when i replaced the radiator i went with a three row radiator instead of two, so i'm assuming there's at least something out there you could use...even if it's just getting a wider one for the 4cyl (pending fan clearance of course).
