Had a antifreeze leak for months. Started looking around and noticed the fitting from the heater core return line into the engine block was corroded and ready to fall of. I barely touched the return line and it the fitting snapped off. I'm the 3rd person I know with this same problem, same vehicle. There is obviously a problem here GM needs to address.
