My BEHR radiator has an anoying weep from the top connector. Having just replaced the head gasket and then the water pump to cure water and oil leaks, I wonder if it is all linked to a change in coolant antifreeze. The connection appears to have a joint in the horizontal plane and I am wary of trying to open this joint as the only retaining feature seems to be the plastic 'clips'. Too much force would snap these and ruin the radiator. Has anyone managed to cure a similar leak without replacing the radiator? Is it possible to super glue or plastic weld it with an adhesive? Any tips would be appreciated.
