This slide presentation is so useful to let us know the importance of a cooling system for a vehicle with the valid reason. You can get details regarding cooling system, types of cooling system and its components. You can also get the maintenance tips of the cooling system.

1. How Car's
Inadequate Cooling
System Causes
Vehicular Heatstroke

2. Why Vehicle need a cooling
system..????

3. A 4 cylinder vehicle produces 4000 controlled explosion inside
the engine while injecting the fuel to cylinder and these
explosion produces huge amount of heat that can destroy the
engine in a minute.

4.  To cool down the over heating of engine,
Cooling system is invented.

5. It consist of a
liquid coolant
that circulates
within the
engine
The coolant can
be cooled by the
air that is
coming through
the front grill of
vehicle
Basic
Work of
The
Cooling
System

6. Current Cooling system : It maintain the engine’s
temperature in a constant position and it isn’t affected by
outside temperature (Ex whether it is 110 degree or -0
degree outside)

7. Is that affect the fuel-economy ..????

14. The coolant
should
contain rust
inhibiters
and lubricant
Coolant must
resist below 0
temperature
without
freezing
Must handle
excess 250
degree
temperature

15. The combination of coolant ……
Coolant is the mixture
of ethylene(antifreeze)
and water
Ratio involves 50:50
Where the climate
condition can be
zero then the
combination is 75:25
Pure ethylene or
antifreeze wont
work properly and
cause a boil over
inside the engine
Coolant should be
kept away from
human or pet reach
as it’s dangerous for
health

16. What are the different
components of Cooling system
…???

17. Radiator
Radiator
cooling
Fans
Pressure
Cap and
Reserve
Tank
Thermostat
Bypass
System
Freeze
Plugs
Head
gasket and
Intake
manifold
Gasket
Heater
Core Hoses

18. Radiator :
The radiator helps the hot coolant to
cool again by the help of outside Air
that comes through the grill

20. Pressure Cap and Reserve
Tank
The pressure cap maintains the pressure
in cooling system up to a certain point
that allows the coolant to reach excess
of 250 degrees of temperature

21. > When the coolant reaches the
highest point of pressure it
starts bursting out
> To keep these overflow and
make use it later the reserve
tank is placed inside the engine
Reserve Tank

22. Water Pump
Helps in moving the coolant from one place to another
till the engine is on . It is located in front of the engine
and starts working when engine starts.

23. Thermostat
The thermostat is a valve that measures the
temperature of coolant if it’s hot then it allows the
coolant to flow towards radiator for cooling down.

24. Bypass System
This is a passage that allows the coolant to flow to
the radiator and after cooling down it can return
back to the engine.

25. Freeze Plugs
These plugs helps to store the
coolant from pouring out. This
plugs are last long with the
engine with no effect of
deterioration .

26. Head gasket and Intake
manifold Gasket
They are used To block the cylinder heads that prevents from
leaking of oil and coolant

27. Heater Core
This is a small radiator system
that maintains heat inside the
interior of vehicle when needed.

28. The hoses are used to do
plumbing that connects the
coolant to needed
components
Hoses
