They are usually horizontally-opposed, for smooth running. These days, automobile cooling systems have parts made from copper, silicon, nylon, steel, and magnesium and aluminum alloys. This inherent reliability as well as the lighter weight is the reason most aircraft with engines under 400hp use air cooled units. (Image: AAA) Why it’s Important to Have the Right Engine Coolant In older cars, engine cooling systems were mostly brass, rubber parts and cast iron, so engine coolants were all pretty much the same. You change the engine oil as in any other engine and the gaseous coolant is air, so no need for complications of a water radiator, many hoses, pump(s), thermostats or all the problems they can bring. My alternative system, using nitrogen, oxygen and argon gases with oil as the coolant inside the engine, is free. From its iconic yellow jug antifreeze/coolant to its innovative stop leak line, the Prestone brand honors its 90-year history by keeping its groundbreaking formulas laps ahead of the competition.

All alternative systems are extremely expensive and barring high performance engines not worth the cost. PRESTONE Since 1927, Prestone has protected drivers and their vehicles with cutting-edge products. Modern cooling systems use additives and closed systems with moderate pressure, so that the boiling point is raised and cooling more efficient. In general for low pressure systems and minimal costs nothing beats plain old water in cost and convenience. Sodium used in nuclear reactors - have extremely high boiling point and thermal transfer characteristics but requires a high pressure closed system Oils - raise the boiling point but require higher pressures Water with a lot of additives - raise the boiling point

There are a lot of other liquids used as coolants

Water is still the best and cheapest coolant.
