Engine cooling system failure: causing vehicle failure,North American HS code tariff structures needing to be dealt with urgently. As an indispensable travel tool in modern people's life, its performance and use effect are directly related to our safety and comfort Suitable for travel efficiency. For cars, the engine is not only its heart, but also the key to its performance and use effect. However, if there is a problem with the cooling system of the engine, it will directly threaten the safety of the vehicle and lead to vehicle failure. This article will start from the following aspects to explain the dangers, appearance and related repair and maintenance measures of engine cooling system failures.I. The engine cooling system is one of the important parts to ensure the normal operation of the engine. When our car is running, the engine will constantly generate heat, and the main function of the engine cooling system is to circulate the coolant into the engine through the radiator of the vehicle, take away the heat generated, and keep the engine always within the safe temperature range. Therefore, the failure of the engine cooling system will directly endanger the normal operation of the engine and bring danger to our driving. The specific performance is as follows: 1. Cause the engine to overheat. If the engine cooling system fails, it will make the coolant in the engine unable to circulate, causing the coolant to overflow at the high temperature of the engine combustion, so that the engine will generate excessive heat inside and cannot cool down, causing the engine to overheat. Overheated engines will reduce fuel consumption and affect engine performance and service life.2. Affect the oil. When the engine cooling system fails, the coolant in the engine cannot circulate into the radiator to dissipate heat, which will cause the temperature of the oil to be too high and thicken or even deteriorate, accelerating engine wear and reducing the service life of the engine. 3. When the engine overheats, the car computer system will automatically turn off several cylinder blocks of the engine, resulting in a decrease in power and unstable idling. 4. When the engine is damaged and the engine is overheated and not handled in time, it will cause problems with more parts, which will cause the vehicle to stop working and lead to damage. II. The appearance of the fault The appearance of the engine cooling failure is not very obvious in many cases, but we can still identify it through the following aspects: 1. The engine radiator tube has water seepage 2. StartThe pointer of the thermometer points to a high position or overheats. 3. There will be a strange clicking sound during the driving. 4. Unstable idle speed or continuous decline in power, and poor fuel economy and other phenomena. III. Maintenance measures The failure of the engine cooling system needs to be repaired in time, otherwise it will lead to serious consequences. So how to repair it? 1. Engine cooling circulation system detection First check whether the cooling system of the vehicle is normal through professional equipment, and test the temperature and pressure of the cooling circulation fluid and the leakage of the cooling system. 2. To check the cooling water pump and water pipe, you need to check the tightness of the cooling water pump and the water pipe between it and the inlet and drain. If some substances are found in the water pump blades, they need to be cleaned up. In addition, it is necessary to check whether the cooling water pump is working normally and whether the engine water tank and other parts are leaking. 3. Clean and scatterWhen there is a stain in the radiator, it will block the radiator and reduce the heat dissipation effect of the cooling system, and the failure of the radiator often causes overheating of the engine. At this time, it is necessary to clean the radiator to ensure that it has a normal heat dissipation effect. 4. Replace the coolant of the cooling system and replace the coolant regularly to realize the process of cleaning the cooling system and eliminating hard water, which can ensure the normal operation of the cooling system. 5. Replace the faulty parts of the cooling system. If faults or serious wear problems are found, it is necessary to replace the faulty parts of the cooling system to ensure that the engine can run normally. In a word, with the increase of the mileage of the car, the temperature control and other parts of the vehicle need to be checked and maintained regularly, and the engine cooling system is the focus that we cannot ignore. Therefore, in daily life, we should strengthenThe inspection of the vehicle cooling system, so as to prevent the failure of the engine cooling system and ensure the safety and comfort of our travel.
