Cooling system

The cooling system in a car is one of the most critical systems to ensure that the engine operates at the right temperature and avoids overheating.

The cooling system in a car is designed to keep the engine within an optimal temperature range during operation. The performance and lifespan of the engine are greatly affected by its temperature, and overheating can lead to serious engine damage.

The cooling system consists of the following components:

• Radiator - It acts as a heat exchanger that is cooled with air when the vehicle is in motion. It receives hot coolant from the engine and lowers its temperature by air cooling.
• Coolant – The coolant is a mixture of water and glycol that circulates through the cooling system. It efficiently moves heat from the engine and carries it to the radiator.
• Water pump - The water pump is a mechanical pump that is driven by the drive belt in the engine. It ensures that the coolant circulates between the engine and the radiator.
• Thermostat – The thermostat regulates the flow of coolant to ensure that the engine maintains a consistent temperature. If necessary, it lets more coolant through the valve.
• Cooling fan - The cooling fan blows air over the radiator when the engine gets too hot or when the car is stationary. This is controlled by a temperature sensor or a thermostat.
• Expansion Reservoir - This reservoir contains additional coolant and provides extra space for the coolant as it expands as the engine heats up, thus maintaining an even pressure.
• Cooling system channels - These are the pipes and hoses that run from the radiator to the engine and are what transport the coolant, they can withstand high temperatures and a high pressure.
