Best Sealent/Epoxy/product to fix crack in Radiator endtank????

Just behind the cap of my Radiator is a very small crack that has been slowly bubling out when the car gets hot. \

I initially used some "plastic Welder" plastc adhesive, but once it was hot, the coolant just bubbled right through the hardened adhesive.


What would be the best type of stuff to use to fill and permanently seal a hole in the plastic endtank of the radiator?

I am probably not working tommorow due to our expected snowfall (4-8" tonight )

so Im gonna pull the radiator and try to seal her up

either JB weld or the "plastic gas tank kit" they sell at advance (permatex sells it, its in a blue box)


i make my own concocktion. this is a really strong bond. buy some 2 part plastic adhesive. also find and old t-shirt or any type of thin non fluffy material (like kakies, t-shirt, old boxers........no jeans or towles.) basicly your making a ghetto fiberglass.


mix the epoxy together and spread it on the area you want. now cut a small peice on the material to fit and put i over the epoxy and press down so it starts to soak up the expoxy alittle. this makes it really strong and the epoxy wont crack and i garuntee it will be sealed. also scuff the srea with sand paper first.
