freeze plugs are pressed into place and look like a upside down juice bottle cap and painted to match the engine and if the engine freezes due to low anti freeze mixture then the plug will pop out but sometimes not completely so fill the engine with a coolant mixture and see if it leaks and follow that leak to see if it is the plug
