Default Core Plug Removal

Any tips to removing the core plug under the starter. I have everything removed around the plug. How do you get it out?

BTW ther reason for removal was it was leaking

core plug = freeze plug?

hit 1 side w/ a screw driver so it rotates/pivots in the hole, then get some vice grips and yank it out... (assuming yours isnt threaded in)

A big screwdriver. Either punch a hole in it or hit it on the side to rotate it then pry it out

Got it out thanks for the tips. I just made a huge hole in it and put a bar to it. Came out with a little love. I am assuming I can just pop it back in with a socket till it is flush. Correct?

yeah, just get a big socket that just fits inside so you get it in evenly.

When I was a kid in the 1950's I had a 31 Cad. V16. I was running water in it & drained it every night . This was in the late fall in Minnesota. I came in late @ nite & planned to get up early & start it & warm it up. The temp got lower then expected & all the freezeplugs popped out . The engine had Popsickles sticking from out of the block.

We've all had cars that we wish we never got rid of in the past...

THATS the best one I have ever heard of! Got to park one of these V-16 Caddys at a golf course I worked at in the late 80's. Didn't really drive it, just pulled it to the lower parking lot, maybe 100yds. Still haven't forgot!

need to smear a little ''form-a-gasket'' on it--goes in easier than dry and the sealant seals....or get a rubber replacement with a built-in drawbolt--you just place it in the hole and tighten the nut in the center of the rubber--napa or most auto parts stores have em--need to know hole size...rubber ones hold where steel ones blow out

redrose thanks for the suggestions. When I replaced I used alittle Gasga-cinch Gasket sealer on it. I am letting the sealer dry over night and will fill in the morning. I hope my problem gone.
