“Expansion Plug – HCC3900687.” Product names and specifications can vary across manufacturers and industries. However, in the context of automotive or engine components, an expansion plug is also known as a freeze plug or a core plug. These are typically metal plugs used to seal or close holes in the engine block or cylinder head. They are designed to pop out if the coolant inside the engine freezes, preventing the engine block from cracking.
