Overheating Car – Causes and Short – Term Solutions

Overheating Car – Causes and Short – Term Solutions

Overheating of the engine not only occurs in the summer, but can also occur in daily driving. In particularly, high-speed running cars, engines, and air-conditioning systems can cause boiling phenomenon when the water temperature is too high. It’s dangerous to overheat the engine. It may hard luck that what can damage the engine. When driving on highways at a higher speed, or when climbing a car, if the pointer of the water temperature gauge enters the red zone and stays high, appropriate measures should be taken at this time. Here’s how to handle the engine overheating.

There are many causes of overheating, including insufficient coolant, cooling fan cooling the coolant has failed, thermostat failure, and coolant temperature sensor failure. If you deal with it improperly, it can lead to an expensive engine failure. Therefore, timely detection and proper disposal of overheating can effectively reduce losses.

What is the effect of engine overheating on the engine?

1. Reduced aeration efficiency, resulting in a drop in engine power.

2. The propensity for pre-ignition and deflagration increases, which disrupts the normal operation of the engine; at the same time, it also causes early damage due to additional impact loads on the parts.

3. The normal gap of the moving parts is destroyed, so that the parts can’t move normally, or even damage.

4. The mechanical properties of the metal material are reduced, causing damage to the part’s deformation.

5. The deterioration of the lubrication condition exacerbates the friction and wear of the parts.

How is the engine overheating caused?

First, poor engine cooling: Poor engine cooling can cause the water temperature in the tank to be too high. When longer the water tank is used, the more internal scale will build up, resulting in poor heat dissipation in the radiator. The water with too high temperature will not release heat, and it will evolve into a “pan”. In addition, the ventilation hole of the radiator is also a common cause of poor heat dissipation. If the external blockage is not ventilated, use a water gun to clean it up. If the inside of the radiator is blocked, then clean it with a cleaning solution.
Second, the cooling system is not working properly, resulting in poor heat dissipation. At this time, check the tightness of the fan belt and whether the fan blades are deformed or broken.

Third, the thermostat automatically adjusts the amount of water entering in to the radiator according to the temperature of the cooling water, so as to ensure that the engine works within a suitable temperature range, which can play a role in saving energy consumption. If the engine is overheated, check that the thermostat is working properly. Starts at 70°C and fully open at 83°C. When the height of the fully opened valve is not less than 9 mm, the thermostat can be put into the water for heating inspection. If the thermostat can’t be opened or the opening degree is not enough, the thermostat needs to be replaced.

Finally, be careful not to shut down the engine when the engine is overheated. If the fan belt and coolant circulation are normal, do not turn off the engine and wait for the engine to cool. Normally, People tend to feel that the engine cools down more easily after the flame out. Actually, after cooling off, the cooling fan and coolant circulation will stop, which will make the engine hotter. There are two spiral fans on the side of the engine compartment bumper. One is a cooling fan that cools the engine while the engine is working, and the other one is an air-conditioning fan that is used when the air conditioner is turned on. Therefore, if the fan belt is not broken when the car is overheated, it is better not to turn off the engine, but also to turn on the air conditioner at the same time, so that the engine cooling rate will be faster.
