What is a Frost Plug?

Frost plugs (also called freeze plugs, engine core plugs, or engine block expansion plugs) are critical to your engine's coolant system. They fill casting holes that are created when the engine block and cylinder head have been cast. Also, if your water freezes, the frost plugs move to release pressure. They keep the coolant from leaking out. 

If the frost plug fails or is broken, your coolant will leak out and cause the engine to overheat.
