コアプラグ
1. Core plugCore plugs, sometimes wrongly called freeze plugs or frost plugs, are plugs that fill the core holes found on water-cooled internal combustion engines. The sand casting cores are used to form the internal cavities in the engine block or cylinder head(s), usually forming the coolant passages. The traditional plug is a thin, domed, disc of ferrous metal which is pressed into a machined hole in the casting. Alternatively a non-ferrous metal such as brass offers improved corrosion prevention.
