There is a chamber wall it sits inside then drops to the bore that you can push it into with your finger then tap inward with a tool. Don't be fooled by the chamber itself it has a tapered lip downward to the actual bore. ]]> 3.0L V6 wayneo https://www.ford-trucks.com/forums/1803809-correct-freeze-plug-sizes-for-the-ford-3-0l-vulcan-1986-2004-a.html
