Finally, other concerns may dominate cooling system design. As example, air is a relatively poor coolant, but air cooling systems are simple, and failure rates typically rise as the square of the number of failure points. Also, cooling capacity is reduced only slightly by small air coolant leaks.
However, uncooled EGR designs do exist; these are often referred to as hot-gas recirculation (HGR). Cooled EGR components are exposed to repeated, rapid changes in temperatures, which can cause coolant leak and catastrophic engine failure. [9] [10] Unlike spark-ignition engines, diesel engines are not limited by the need for a contiguous ...
a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine; a water pump, usually of the centrifugal type, to circulate the coolant through the system; a thermostat to control temperature by varying the amount of coolant going to the radiator;
The Model A engine uses a centrifugal water pump, mounted to the engine cylinder head, and it works with the engine fan. The Model A engine uses plain water to cool the engine; antifreeze coolant is not recommended because the original Model A radiator is not a pressurized system. The pump circulates radiator-cooled water into the lower engine ...
A barb (or hose barb), which connects flexible hose or tubing to pipes, typically has a male-threaded end which mates with female threads. The other end of the fitting has a single- or multi-barbed tube—a long tapered cone with ridges, which is inserted into a flexible hose.

The result is pitting of the cylinder wall, which will eventually let cooling fluid leak into the cylinder and combustion gases to leak into the coolant. It is possible to prevent this from happening with the use of chemical additives in the cooling fluid that form a protective layer on the cylinder wall.
