Broke off block drain plug
 

My problems continue, I snapped off one of the blue plastic drain plugs. Any suggestions on how to get it out. Is it a pipe thread ??? I do not think a drill will fit down in there.

I believe that the blue plug screws into a fitting that screw into the block. The block is pipe thread and the blue plug is Acme.

put a wrench on the brass housing it is threaded into & take out the assembly.. Then you can either work out the blue plug and just replace it or you can replace the whole little assembly. If you need replacements feel free to give me a shout.. :) Hope this helps.. :)

I've found most times you can jam a socket extension end into the broken plastic plug and it will screw out.

Thanks for the help. I did not know that the blue plug was screwed into a brass fitting. I can barely reach it let alone see it.

i used a pocket screwdriver once, and it came right out.

Also you can use a Torx bit driven into it then back it out.

You might also try a left handed drill bit in a pair of small vice grips. This worked for me once. I like the external torx bit idea; I'll remember that one. That and an external hex bit might work too in a pinch.
