What is the cooling system in a car?
The cooling system is the system responsible for cooling the engine or maintaining its temperature, if you will, to be within the operating temperature that guarantees its work as required to give the best performance with high efficiency, and the operating temperature is the temperature at which the engine must work and calculated accurately by the car manufacturer.
Every internal combustion engine needs a cooling system because the engine needs a combustion process inside the cylinders to produce energy, and this combustion of course generates very high heat, and if this heat remains inside the engine, it will be damaged and its internal parts will be greatly damaged.
The engine is cooled through water or coolant that is inside the cooling system, where the cold liquid enters the engine working through the water pump, then circulates inside the engine block in order to withdraw its heat, then the hot water returns to the radiator in order to be cooled and returned to the engine.
As long as the engine is running, it needs the cooling system to draw heat from it, and if a component of the system malfunctions, the cooling process will not be completed or may be weak, and this will affect the work of the engine without a doubt, and sometimes it may fail completely.
Therefore, if you want to buy a used car, you should go to Motorgy, because it puts in your hands used cars for sale in Kuwait at the best prices, accompanied by an inspection report for the most important parts, including the cooling system and the engine, so you can buy the car you like without troubles and subsequent hassles.

The most important issues with cooling system
As for the most important issues with the cooling system in the car, they are:
Warning light comes on
If you notice that the engine temperature warning light, check engine light, or any other warning light is on, it may mean that there is a serious malfunction in the cooling system, so it is always best to have your car serviced at least twice a year to ensure the safety and readiness of the cooling system and other parts of your car and to resolve any issues that may be discovered during the inspection.
Coolant leaks
One of the most common cooling system issues is the leakage of coolant out of the system, and the liquid can leak from several places such as the radiator, hoses, engine block, water pump and other parts, and if the percentage of liquid in the system decreases, the cooling process will malfunction and the engine will gradually heat up, and you may notice white smoke coming out of the exhaust due to the burning of the coolant inside the cylinders after it has leaked into them.

Air entering the cooling system
If air enters the cooling system, it may reduce its ability to maintain the proper temperature of the engine and regulate its performance, and the symptoms of air entering the system are overheating or fluctuating high and low temperatures, and excess air inside the system may sometimes lead to the formation of great pressure inside the hoses and the radiator, which may burst from the intensity of the pressure.
Thermostat damage
The thermostat is the part responsible for allowing the hot coolant inside the engine to exit the engine and go to the radiator to be cooled, it keeps the temperature of the coolant within the required rate inside the engine, and if its temperature rises more, it opens to pass the liquid to the radiator, and if the thermostat is damaged and remains closed, for example, the engine will overheat and may fail if you do not pay attention to the heat meter.

Damaged water pump
With the water pump working for a very long time in the car, rust will accumulate on it and cause corrosion and corrosion of the fan inside it, which may lead to small holes on the surface of the pump and water will leak from it if you do not pay attention to it, and rust may often be accompanied by loud squeaking sounds coming out of the pump, which is usually in the front side of the engine.
Damaged head gasket
The head gasket acts as an insulator between the cylinder heat and the engine block, and when this gasket is damaged or cracked, the coolant will leak and air bubbles will form, causing the engine to overheat quickly, and even lead to other serious engine issues.
