What is a Core Plug?

Core plugs (frost plugs, freeze plugs, and engine block expansion plugs) are vital to your engine's coolant system. They plug the holes that are left when the cylinder head or engine block has been sand cast. 

If in an event where the coolant freezes and expands, they are designed to move to release pressure. If a core plug fails or is damaged, it can allow coolant to leak out, causing the engine to overheat.
