Cooling System

Cooling systems are an important part in our cars because they cool the engine as we go along the road to our destination . Most people forget that their cars needs water or coolant to cool down every now and then because if your car heats up that means a lot of water and a bit of coolant is wasted , Why i said a lot of water because water becomes gas before its boiling point under pressure meaning starts to turn to steam when the temperature gets to 85-95 C . that is why car manufactures and proper technicians say u need to use coolant instead of water , enough about that ! , there r two main types of cooling system in our vehicles .

1. Air Cooling System
2. Water Cooling System

Air Cooling System :-

                                Its a system which cools the engine by air which is passed through the fins which absorb heat from the cylinder directly and cools the engine . It is mostly used in Motorbikes and electronics ( Like Computers ) now a days but it was used in the legendary Volkswagen Beetle 

Advantages:-

1. The engine with a Air cooling system was much cheaper to make because of it low material and parts.
2. It took only a small amount of space on the engine and the vehicle.
3. It was Easier to maintain a car with Air cooling system (its maintains was cleaning the fins and that's it ).

Disadvantages:-

1. It could not cool the engine properly in High Temperature regions like Middle East.
2. It is less effective when the car is stationary because in a stationary car the air is not going through the fins to cool it down .
3. It could not cool down the engine properly since the engines life is deceased due to heat and the ware it causes in the engine

Problems and Causes :-

                                      Mostly it does not cause any problems unless u damage the cooling fins or there is too much dust and dirt between the fins which provides resistance for the air which passes through the fins to cool the engine .

Water Cooling System :-

                                         This type of cooling system is widely used in cars now a days , This system cools the engine by flowing cool water or coolant near the hot cylinders inside the block , As shown on the side the cooled water  or coolant is drawn by the water pump which throws it inside the block water jets which goes near the cylinder where the explosions are taking place , its only separated by a wall between the cylinder and the water jets which becomes hot when combustion takes place and the water carries the heat from it to the radiator outside the block where it cools down the water or coolant which goes back to the jets to carry the water or coolant back to the jets to carry heat and vise verse

Advantages:-

1. It is more effective in all weather conditions
2. It provides more cooling to the engine because of its continuous flow of water even if the car is stationary or uniform.

Disadvantages:-

1. It requires more space in the vehicle because it has more parts then the air cooling system.
2.  It has more maintenance then the air cooling system
3. It cost more to manufacture since it is expensive

Problems and Causes:-

                                    There are many problems which could occur in a water cooled system 

• Thermostat valve not working : this means that the water or coolant inside the block will stay inside the block and circulate in it constantly without going to the radiator for cooling.
• Radiator Fan : If the fan is not working the water coming to the radiator will not cool down which causes it to evaporate thus the engine starts to become hotter then usual .
• Water Jets Leaking or seal Leaking : this means that there is a leak in the system by which the water or coolant is flushed out of the lines and radiator causing temperature rise .
• Radiator Cap : Yes ! radiator cap also plays an important part in it if the radiator cap is not properly put or the rubber or valve is not working it would leak out all the water or coolant or evaporate all of it .
• Cooling Grills : Cooling Grills must be clean so that the air can pass easily through it to cool down the water , if choked the water will not cool down hence rise in temperature will occur.
• Water Pump : if fan belt is lose or the water pump is rusted up it would not throw the water inside the engine block causing to over heated engine
• Reservoir : The reservoir also play an important role in the cooling system , It gives and takes extra water or coolant when vacuum or pressure is created inside the radiator.

Hope this was Helpful ! Pardon my lack of knowledge if any mistakes
