Radiator leak

Well, after reading about how terrible the radiators are for this truck in the last 10 years of me owning one it finally happened.
What are some solid replacement solutions? All Ears.

Thanks~

Went to Rock Auto first of course and found this radiator by CSF which I've seen mentioned before as a high-quality unit but only for their all-aluminum radiator. Not sure I want to shell out that much just yet being as my plastic OEM unit lasted all 10+ years of my ownership and quite possibly the first 6 years of the truck's life.

Any thoughts?

More Information for CSF 3642

Radiator

About 6 years ago I went with the Mishmoto all aluminum radiator and it has been working great.

From what gather its not really the radiators that are junk, its the flex of the core support that's causing otherwise good radiators to crack.

When you say core support, do you mean the frame on the truck which it’s mounted or the actual structural integrity of the radiator?

The parts of the body the radiator bolts to. One piece is even removable at the top. The rest is part of the body/ cab structure , not part of the vehicle frame (there are even two body mounts below it. See the red circled areas in the pic below. From what can tell, this is what flexes out of shape (most likely due to bad/ deteriorated body mounts) and cracks the radiators.
