Welch plugs (core plugs) are circular discs that fit into, and seal the casting and machining holes in the Engine block, Cylinder head and Transmission. You may hear them called "welsh plugs". They are often called "freeze plugs" because if the engine coolant freezes they'll be pushed out of the casting. However, their purpose is not to solve freezing problems but rather to seal the holes left by the casting or machining process.
