The construction of the block heater is this: The metal plug you're pulling on has an o-ring groove cut in it. There's an o-ring in there, of course, to seal the hole. The plug is corroded to the block. That's why it's hard to remove. I'm guessing you're taking it out cause it's not working? If so, you can get rough with it. Yard that sucker outta there. Now the uh-oh part: The bolt in the center screws into a t-nut behind. When you took it all the way out, the t-nut fell down in the block. You will probably get it out with a magnet. Let's hope it's easy! ;D
