In the last post I explained about automobile cooling system . Now i am continuing
from where I left last.
In this post I will explain the working of various components of cooling system.
The following are the main components of a water cooled engine.
Water Jackets
Water jackets are the ports in the walls of cylinder block and cylinder head for the
passage of cooling water. The cooling water passes from these ports and carries the excess heat
from the engine.
Thermostat Valve
The Thermostat valve is used to regulate the circulate of water in the cooling system to maintain a normal working temperature of engine.
it consists of a valve , spring and wax .When temperature increases the wax melts and the valve opens and the water starts flowing to radiator. when the engine is cool, thermostat prevents the flow of water to the radiator. the water circulates inside the jackets only and working temperature is maintained. when engine temperature increases the thermostat valve opens and the water flow to the radiator. The valve opens between 85 to 100 degree Celsius depend on the manufacturer's specification.
the thermostat valve consists of a wax filled pellet which contrast when cool and expands when hot. when the temperature rises the wax melts and allow the water to flow.when temperature decreases the wax contrast and the valve is closed by a spring retainer.
Radiator.
radiator is used to cool the hot water coming from engine. The water cools down with the contact of air.
The radiator consists of an upper tank, a lower tank and core.
The hot water enters in the upper tank of radiator and flows to the lower tank through the core.
while the water passes through core the heat from water is removed.

In this post I will explain the working of various components of cooling system.
The following are the main components of a water cooled engine.
- Water jackets.
- Thermostat valve.
- Radiator.
- Radiator cap(pressure cap)
- Surge tank..
- Cooling fan.
- Water pump

Once I found out just how easy it was to change my airfilter, I realized that I had always overestimated small maintenance. Can’t wait to get to work on my Swift. Manyautosltd.com is my car doctor and I really appreciate their team for being such sweetheart best car service in reading
