Should I bother with some kind of stop seal for the radiator or should I look for a new rad? I will be checking levels and under the truck when cool.

Seems to me that some of that stuff does occasionally work, but I hate the thought of clogging everything up with something- I can only image that if it will stick to a leak, it’ll stick a lot of other places too that are unwanted maybe wouldn’t cool as well after that, but that’s just my thought.

@ChuckN you recently replaced your rad didn't you? What did you go with again?

I wouldn't add a stop-leak. There's really no magic fix for a radiator with plastic tanks. Imho, just buy one from a local parts store with a lifetime warranty... then remember where you bought it ten years from now, lol.

I went with a Cold Case. I used the code for Vice Grip Garage for free shipping- make sure you get the one with the 1.5” lower outlet.
I definitely recall the problems you had with the lower outlet being the wrong size now...
