Can anybody tell me the proper way to install freeze plugs on a 440.
Do you just pound them in or do you put some type of silicone on them and then pound them in. Appreciate any help

 

I can only help with what not to do, but it's a lesson well worth knowing.

DO NOT settle for those freeze plugs that have a screw in the middle and expand as you tighten them in. Yes they are much easier to install and they also are junk! You don't want to loose one traveling down the road with a non-working temp gauge. Back in the mid 90's those things cost me a '69 383

I prefer to use cup type brass freeze plugs.. They make a tool to instal them. But a good sized socket and a 1/2 extension works in a pinch. Use a 3-5 lb sledge hammer. Do not use any silicon. maybe a little Form a gasket

 

you MUST use some kind of sealant on the inside of the plug (the side that is not seen and is in the block). just use a hammer and a socket that fits the plug, just make sure it goes in straight. i dont use anything but brass i would suggest you do the same.
