How much am I looking at to fix a leaking radiator on a 96 chevy tahoe?

JB weld for metal. On plastic caps or the rad itself. Yes, the stuff for metal on the plastic caps works.

On the rad, drain coolant below the leak, clean surface, 50/50 mix. On the caps, drain coolant below the leak, ruff up surface with a wire brush, clean and prep with alcohol, 60/40 mix. Light on the hardener.

Either way, let cure for 24 hours. Should be good for whats left of the life of the rad. I've done three.

2-7 yrs old. Still holding. If it's leaking at the plastic cap seal, you're done.

New rad time.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
