core plug


core plug
A metal plug located in the sides of the engine block which can pop out because of excessive pressure or freezing and prevent the engine block from cracking. These plugs are located in the water jacket and can sometimes leak and should then be replaced. Block heaters are installed by removing a core plug and inserting a heating element. Core plugs are also called "freeze plugs" or "expansion plugs."
