Bulletproof cooling system

The automotive radiator is essentially just another name for a heat exchanger, whereby combustion temperatures are transferred to the cooling system of the engine block and taken outside the block via flexible radiator hoses to be exposed to the cooling force of air through the radiator core, thus reducing the temperature of the coolant before returning it to the engine block. There are two restrictions in the system. One is the thermostat, which restricts flow and holds heat in the engine until warmed up, and the other is the radiator core tubes. The radiator tubes have to be of sufficient size so as to allow the coolant to flow through in an unrestricted manner, but also able to 'scrub off' BTU's or heat; which is based on the shape of the tube and the convection of heat away from the coolant to the outside air. A wide flat tube will expose more surface area to the outside flow of air than a narrow tube. The reason for this is more surface area is exposed to cooling. Look at the pictures located below and see why that is.
