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
