I agree that cooling system is complicated system because its need to pressurize.
#3
advantage of water:
-water one of the most effective fluids for holding heat;
disadvantage of water:
-water freezes at a too high temperature
#4
The boiling point of coolant raises by pressurize the cooling system. Its necessary because the temperature of the coolant can sometimes reach 121 to 135 C and these temperature would boil the coolant.
