Thanks but I'm not going to replace all of the core plugs. The engine is not coming out of the vehicle and I don't have enough room to pound in a brass or steel plug.

I intend to use the rubber expansion plug with the wing nut on the end for ease of installation.

I assume, from the sizes lifted above that the one I'm going to replace is 2 in in diameter. I just want to know before I knock the old one out so I can have a new one ready to go in

What would be the best way to remove the existing plug? I don't want to accidentally knock it into the water jacket. And I don't want to break it into small pieces that might fall in.
