Coolant reservoir 

It’s also called as radiator overflow tank. It collects the expanding coolant that’s heated by the engine and and resend it to the cooling system when it looses enough heat. As the engine coolant heats up, it expands and build pressure. When the pressure exceeds a optimum level, the excess coolant is transferred into the


Why do we need a fan!!?, Here’s the answer The RADIATOR needs a constant flow of air through its core to cool it adequately. However it happens when the car is in motion but when it’s stationary a fan is used to help the airflow which would be driven by engine power. When the engine


Many people find the radiator pressure cap on their vehicle but don’t know the purpose of it. Many think that cap was for more than just show. In fact it plays an important role in a pressurized cooling system. When you set the vehicle into motion the temperature of the engine increases. We know that

Confusion of Chassis and Frame

You must have heard car technicians using the term Chasis or vehicle Frame many times but for a common car driver or a non-car guy, it is difficult to make difference between both. This confusion has arisen due to a large change in the built of cars coming up in the market in a very


So far we talked about air cooling system: How it works, components of it, why do we need fins.., In this post we will talk about liquid cooling system almost every automobile using. Before get into working I wanna let you know all the components of liquid cooling system.  Liquid cooling system:  A liquid (coolant)


The components of most air cooling systems are quite simple. A fan or blower is installed in air cooled engine to improve air flow over the fins. Most engines that use blower fans also use shrouds or ducts to make sure the cooled air flows over the fins. There are 2 classes of fan used in

DESIGN of air cooling system:

Don’t think we just need fins on Engine components to take of all the heat from the Engine. We have to learn how to direct the air flow in such a way to get high efficiency in heat dissipation  which we will discuss in this post. Before getting into it let me introduce you some
