Gasoline
engines have
improved through the years; however, it is still necessary
to use cooling system to help distribute the heat from
inside of the engine combustion chamber. The proper
distribution of heat, which is the primary function
of the cooling system, is necessary for an efficient
function today's performance engine.

Cooling system must function properly because if it fails to perform its designated task, it will not be able to keep your engine cool causing it to
overheat and possibly totally destroy the
engine. With a malfunctioning cooling system, the engine will emit more pollution and will perform less
efficiently. Causing your Mustang, Cobra, or Mach 1 to slow down and loose that race.
Because the engine is the heart of the vehicle, it is necessary to take care of the cooling system. Perform daily maintenance of the cooling system
checking for leaks and low fluids. It is thus necessary that you check the cooling system and subject it to regular maintenance to help in the proper functioning of your engine, and in
turn, your vehicle will cool properly and performance to its peak performance. You can lower the temperature in your Chevy Corvette, Camaro,
Pontiac Firebird, Tran Am and don't for get the GTO. Keeping all of those performance autos at the coolest temp possible.
MAIN COMPONENTS OF THE COOLING SYSTEM
1.
RADIATOR: Cools off the anti-freeze/coolant mixture by allowing air passing through the tube/fin area to dissipate the heat generated by the
engine combustion process.
2.
WATER PUMP: Draws the cooled anti-freeze from the radiator and pumps it through the engine block, cylinder head(s), heater core and back to the
radiator.
3.
FREEZE PLUGS: Is actually a steel plug designed to seal holes in the engine block and cylinder head(s) created from the casting process. In
freezing weather they may push out if there is not enough anti-freeze protection especially in the colder climates.
4.
HEAD GASKET /TIMING COVER GASKET: Seals the major parts of the engine. Prevents oil, anti-freeze and cylinder pressure from mixing together causing
loss of power and flooding of cylinder with coolant.
5.
HEATER CORE: Provides heat to the interior of the car by using heat removed from the antifreeze and blown in by the blower motor. May cause
steam, coolant odor or actual dripping inside the car when it leaks.
6.
THERMOSTAT: Controls the minimum operating temperature of the engine. The thermostat is closed when the engine is cold in order to speed warm-up and
opens when normal operating temperature is reached to allow the anti-freeze/ coolant to pass through the radiator.
7.
HOSES (Radiator, Heater, By-pass): Connect the other main components of the cooling system. Hose manufacturers recommend replacing every 4 years
regardless of appearance because there may be deterioration of the inside of the hose which cannot be seen.
8.
FAN CLUTCH: Senses the temperature of the air coming through the radiator and either slips or binds up to pull the required amount of air through the
radiator.
9.
ELECTRIC COOLING FAN: Most front wheel drive cars use this because of the transverse mounted engine. It is turned on by a system of sensors and relays
when the engine reaches about 230° F and stays on until R is cooled to about 200° F.
10.
Block: When our bodies feel cold, we put on a jacket. Our car engines wear permanent jackets for the opposite reason to keep cool! The water
jacket is a collection of passages within the block and
head. These passages let the coolant circulate around the "hot spots" (valve seats and guides,
cylinder walls, combustion chamber, etc.) in order to cool them off. The engine block is actually manufactured in one piece with the water jackets
cast into the block and cylinder head. At normal operating temperature, the water pump forces the coolant through the head gasket openings and on into
the water jackets in the cylinder head. It flows around in there, cooling everything off by absorbing the heat. After doing its thing, the coolant
flows through the upper hose to the radiator where it releases the heat. Then, the water pump sends it back down into the engine's water jackets to
continue the cooling process. On the sides of the engine are "freeze" or "expansion" plugs, which are sheet metal plugs pressed into a series of
holes in the block. These are designed to hold the pressure of the cooling system, but to pop out if the coolant in the block ever freezes.
All of these parts of the cooling system are necessary to ensure your engine works properly. In turn, if your engine works properly, your mussel car
will likewise work efficiently.
