6 reasons why your car’s radiator malfunctions and raises its temperature

A car radiator is a device that contains two basins.. an upper basin and a lower basin. It is connected by tubes from top to bottom and contains an upper and lower opening. These tubes are surrounded by a very thin metal layer that helps increase the surface of heat exchange with the outside medium. The water pump draws very hot water from the engine and pushes it into the upper hole in the radiator, which in turn enters the upper basin in it and begins to descend into the lower basin. During its descent, it loses its heat as a result of the strong passage of air through the layer surrounding these tubes, and the air is produced by the cooling fans installed on the radiator from the outside.

Reasons for car radiator malfunctions

6 reasons why your car's radiator malfunctions and raises its temperature

1 – As a result of using non-distilled water or irregular coolant fluids, calcifications and dirt occur within the fine metal tubes in it, and thus leads to blocking them, and thus the radiator loses a lot of its performance and the process of cooling the water decreases, and therefore the temperature of the car begins to rise, and we can know this by touching the hot upper inner tube and the tube The lower cold outside, and there must be a big difference between the entry and exit temperatures. In the event that we do not find this difference, we make sure that the radiator needs maintenance, which is the process of dismantling the upper basin of the radiator and inserting metal skewers within the radiator tubes to get rid of impurities and lime accumulated in them, and thus clean it completely, then re-welding the basin upper

2 – As a result of the car’s foot and vibration, the radiator welds may be exposed to disintegration, and thus water leakage from it, which requires a re-welding process and leakage control.

3 – As a result of the car running, dirt and insects will accumulate inside the radiator and lead to blocking and preventing air from entering through it, thus losing 80% of its performance. It must be cleaned with a soft brush as much as possible, and avoid directing the water pressure of the washer hose directly to it because the water pressure may cause blockage of the air ducts.

4 – The use of non-distilled water leads to its freezing in winter, and according to the properties of the water, as its volume increases and thus leads to cracking in the inner walls of the pipes.. In order to avoid this, attention must always be paid to the radiator water being distilled water with antifreeze added to it to get rid of this problem.

5 – As a result of the exposure of the car while traveling at high speeds to flying stones from other cars, this leads to the entry of these stones, piercing the radiator tubes and leaking water from it, and then the radiator must be dismantled and welded. For modern cars, it is preferable to change it completely because it is useless to weld it, especially since the modern radiator is made of aluminum unlike The old radiator, which was made of copper.

6 – The upper radiator cap is one of the most common reasons that lead to a shortage of water from the circuit. It contains a compressor cap that locks the pressure inside, but damage may occur in this cap or gasket, which leads to leakage of water vapor from it, and a large percentage of cars that lack cooling water have The problem has been solved by changing the radiator cap.
