Durable steel freeze plugs from Dart work like expansion plugs. As we all know, water expands when it turns to ice, and if the coolant in your vehicle doesn't have enough antifreeze protection, it can freeze and then crack the engine block. Dart freeze plugs are designed to pop out under such conditions to relieve the pressure on the block, thus protecting it against freeze damage.
