 As we aware that every work producing system will produce heat.So it is necessary for the manufacturer to make sure that the heat produced should be controlled.So the first question that comes to our mind " why is engine cooling system needed?" This task is accomplished by the Engine cooling system.As the work produced by engine is through the combustion of fuel. Out of which only 65-70 % is used and 30%-35% is lost as exhaust gases.The temperature of the gases being upto 500 degrees, Some of that heat gets transferred to the engine parts.If they get overheated it may reduce the life of the engine. So, engine life gets reduced. After answering the first question in a simple way.. Let us see the " Types of Engine Cooling System" They are basically classified into 2 types based on the type of Coolant used. Air cooled system. Water cooled system.   1.  Air cooled System As the name itself suggests the air is the cooling medium.As the cooling rate of this type of syst...

 If you have visited a any vehicle repair shop, you might have observed that the car wheel will be connected to a computerized machine ,where the operators do adjustments and try to correct the wheel position.In short wheel alignment is correcting steering geometry.On a technical note it is maintaining the castor angle,camber angle,King pin inclination and Toe-in and Toe-out distances.  While manufacturing any vehicle, the manufacturer will have certain angles in which the wheels are connected to the axle. For proper driving of the vehicle those angles has to be maintained. to maintain those angles wheel alignment is done.You may think once the manufacturer has fixed the angle,why will it change. But in reality, due to vehicle  movement in irregular roads the alignment  changes. If  it is left unnoticed, it may lead to wear and tear of tyre and vehicle may not have straight line stability and may start sliding to one side.The main reason of wheel alignment is to...
