Your 2001 V6~4.0L~SOHC radiator problem seems near identical to mine just a year ago now.
Replaced the original 2RowPlasticTankedRadiator with a new 4RowAllAluminumRadiator.
No regrets,; should have done this years earlier.
Noticed on another forum, you had a question about the TransCooler fittings;
I ground the original compression fittings down by about a 1/2" & then they fit the new radiator,
& can still be used on the old style radiator if reverting back to that for any reason.
See the link below for detail pics on doing this.
Not shown in the pics, but also modified original 1piece fan shroud into a 2piece Upper+Lower;
got tired of wrestling original shroud around fan; easy access to belt\fan\clutch\pump now.
