I am trying to locate the "Freeze Plugs" on my 92 Ford Ranger V6 4.0 liter. I understand what they look like and that they are hard to get to... Even harder seeing as my truck is 4x4.. If anyone can describe them to me, that would be awsome. And if anyone is in the Tulsa Oklahoma area that might be able to lend some advice that would be awsome too. Thank you all..
