You do know that they're not intended to pop out when/if the coolant freezes...right?
They pop out, sometimes, but it's mostly pure luck.
They're intended as openings to remove the sand cores when the block is cast. Which is why it's better to call them "core plugs" than "freeze plugs".
No, didn't know that. Had always heard them called freeze plugs, but I have heard "core plugs" sometimes. Makes sense. Thanks.
