Whats the secret to installing rubber freeze plugs so they dont pop out?

Answer 1

The point of a rubber (or any other kind of) freeze plug is that whatever the plug in in is not SUPPOSED to freeze and the freeze plug is a last-ditch effort to protect the inside of whatever the plug is in (a car engine I assume?) from the damage caused as the liquid expands as it freezes. The plug is the last line of desperate defense from abuse; you need to take precautions (like filling your radiator with antifreeze) that will PREVENT the ice from forming. 5/5/2009: I decided to install a rubber freeze plug in my vehicle. According to the directions on the back of the package, the washer that sits behind the nut, should be almost flush with the engine block. The nut should be turned 2-3 complete turns for the plug to properly seat.
