Although gasoline engines have improved a lot, they are still not very efficient at
turning chemical energy into mechanical power. Most of the energy in the
gasoline (perhaps 70%) is converted into heat, and it is the job of the cooling system to take care of that heat. In fact, the
cooling system on a car driving down the freeway dissipates enough heat to heat
two average-sized houses! The primary job of the cooling system is to keep the
engine from overheating by transferring this heat to the air, but the cooling
system also has several other important jobs.
The engine in your car runs best at a fairly
high temperature. When the engine is cold, components wear out faster, and the
engine is less efficient and emits more pollution. So another important job of
the cooling system is to allow the engine to heat up as quickly as possible,
and then to keep the engine at a constant temperature.
In this article, we'll learn about the parts
of a car cooling system and how they work. First, let's look at some basics.
