The male end of the radiator on the return line has snapped any suggestions?

 

you can try to tap the hole and epoxy in a threaded brass hose barb or take to a radiator shop (if they exist, you may need to call some shops and ask who they send their radiator work to) and they may be able to replace the top. Otherwise new radiator time.

 

Thanks just finished, works! I dont know what I would do with out this forum.

 

Carlos, better order a new radiator, when that nipple breaks off the plastic is fatigued from heat and will not hold, causing it to blow again and possibly damaging your engine.
You can buy good after market radiators for around $200, stay away from used ones cause they are usually plugged and or have e brittle plastic.
