I have a corroded freeze plug I need to replace on my 1960.
![]() Maybe someone here has one or two they want to get rid of (Sell me) saving me even more time. The one I need to replace is just over the motor mount on the passenger side. May be easy to remove except I have the AC/pump mounted over it so maybe the proper puller can fit in there.. Thank you! |

Corroded/? had to be steel than. brass plugs never do that. ALWAYS use brass. not a place to compromise.
Either 1 15/16" or 1 61/64" both work fine. Hope this helps you

Thanks for sharing the video. MY 1957 has one rust perforated expansion plug in the cylinder head, and perhaps another 1 or 2 on the back of the block behind the transmission. Your video is convincing me I should probably pull the transmission and the engine and replace all the freeze plugs.
I just hope I don't find a cracked block instead of a rusty expansion plug when I drop the transmission.

If one is rotted the rest aren't far behind. If you have any chance do them all.
