Thanks, Denny.
Well, this is where you'll find the radiator, and this is what it looks like.
And here's how it works. "In physics you
learn how the cooling system carries of the heat."
A car's engine generates a lot of heat from the internal combustion
that creates its energy.
Unless that heat has somewhere to go, it
will simply build up in your engine and cause severe damage to engine parts.
The radiator transfers that heat out into the air,
but in order to do that, the heat has to have a way of getting there.
That's where the coolant,
somewhat confusingly known as antifreeze, comes in.
This fluid is a mixture of water, dye, and a chemical called glycol.
Ethylene and propylene glycol not only help prohibit freezing, they also
increase the fluid's boiling point and help transfer heat.
As the hot coolant circulates through the radiator core, heat is conducted to
the outer surface, made up of hundreds of these aluminum fins and dissipated
into the air.
Now as you can imagine, having a lot of water and glycol sitting inside a lot of metal
with temperature extremes over time is a formula for corrosion.
Now your service technician
can detect the amount of corrosion with these pH strips.
Now if the word corrosion doesn't cause you to stop and think,
think of it as dissolved engine. When the flow of this coolant in your radiator
is choked off by a build-up of corrosive deposits, your engine will
overheat, and that means you can burn up a lot of money with it.
