Where are the freeze plugs?

Answer 1

freeze plugs are located along both sides of block also at rear behind the flywheel.also have smaller freeze plugs in heads these plugs are used to fill holes that are left in the block and heads after casting at manufacture. the holes are there to facilitate the removal of sand used in the casting, otherwise the blocks would be a solid lump om steel with no water chambers contrary to them being called freeze plugs, they do not stop an engine freezing and certainly do not come out of block when coolant does freeze if this happened we would not get cracked and broken blocks in boat engines that were not winterized in time for the winter and most boat engines are just a marinised car engine
