Science Abuse Posted January 11, 2011 Report Share Posted January 11, 2011 (edited) How much force is necessary to put a freeze plug back in? Or rather, a new one. I have access to the port it popped out of, can I do this with a hammer and big punch? Should I run some RTV or JB weld around the edge?

AJ Posted January 11, 2011 Report Share Posted January 11, 2011 yes you need some sealant around the edge. i like using GM engine sealant because its the best stuff out there. Permatex gasket maker in the metal can is a very close second. you need as big of socket that will fit inside the freeze plug and a hammer. it doesn't take much to put them in so go slow.

You mean it doesn't take much to push them THROUGH? I'm having visions of that right now, I think I can cobble together a simple tool that will tap them in without being able to fit through the hole. The engine is still in the car, so it would be nice to have something that doesn't require finesses and babysitting. Quote Link to comment Share on other sites More sharing options...
AJ Posted January 12, 2011 Report Share Posted January 12, 2011 yes they tap in pretty easy if you go too much they will go through and you'll have to pull it back out. Quote Link to comment Share on other sites More sharing options...
AJ Posted January 12, 2011 Report Share Posted January 12, 2011 green "retaining" style loctite is the preffered method of sealing a freeze/core plug depends on who says that. GM says engine sealant for the freeze plugs in the cylinder heads on LSx engines. so both will work. Quote Link to comment Share on other sites More sharing options...

I'm inclined to go with what I have. Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted January 13, 2011 Author Report Share Posted January 13, 2011 That was actually 10x easier than draining the system in the fall... that is, if I'd drained the system in the fall. Quote Link to comment Share on other sites More sharing options...
