PURPOSE OF A COOLING SYSTEM
Your engine creates up to 5,000 degrees of heat within the combustion chamber. Enough heat to melt
the entire engine in less than 30 minutes! Approximately 1/3 of gasoline’s energy is converted into
usable power to propel the vehicle, 1/3 of the energy is dissipated out through the exhaust system,
and the remaining 1/3 is carried off by the cooling system.
HOW DOES A COOLING SYSTEM WORK?
Coolant, which is a mixture of water and ethylene glycol (Antifreeze), is pumped throughout the
engines water jacket drawing heat from the head, pistons, combustion chambers, cylinder walls,
valves, etc. The heated coolant travels from the water jacket through a radiator hose, to the radiator,
where aided by a fan, its air cooled and returned via the other radiator hose to the engine. Gas is
SAVED and engine life INCREASED when the cooling system quickly reaches and maintains a very
narrow operational range regardless of outside temperature extremes or engine load demands. Upon
engine start up, the temperature must rise quickly, and then remain balanced – not too hot and not too
cold! It’s important to understand how the condition of the coolant and the condition of the cooling
system components can affect the operational economy and life of your engine!
ASTM D3147 LABORATORY TEST
