The hose that attaches to coolant reservoir and to the radiator has broken off at radiator with only a couple threads left but not enough to clamp hose back on. I'm hoping a heater hose connector will help. Or a brass hose barb. How do i get broken plactic attached to radiator off so i can put on a new connector? Also what size do i buy? 1/2 by 1/2? I have no idea where to find the size needed.
