I called a radiator repair shop and he said I may not be pushing it in far enought or not have it aligned correctly or
he said the ears it engages to may have broke inside the radiator.
Said I may need a new raidiator. Cheap plastic crap.
I bought a new drain plug and removed the old plug but the new plug will not go in. tried to put the original plug back in and in will not go in now. Both just turn with out engaging to tighten up.
Any ideas Im stumped???
