You will NEVER find coolant/water/antifreeze in the oil. The gaskets don't leak that way. The ring that seals the cylinder bore to the head fails, allowing the ignited fuel/air to escape the combustion chamber, super heating the coolant. This is why the car overheats, because the cooling system can't cool the coolant as quickly as it is super heated.
