When the temperature rises, the phenomenon that the engine malfunctions due to its own overheating is also increasing. Sometimes when driving on the road, it is found that there is a lot of hot air under the car cover. Stop and open the car cover to see that the water in the water tank is "boiling" and splashing out from time to time. There are many reasons that cause a car to have this situation. High temperature, overloaded operation of air conditioners, and failure of heat dissipation components will inevitably affect the heat dissipation of the engine. In addition, when driving in urban areas, frequent starts and stops will aggravate the friction of engine components and cause the temperature to rise. Especially the long-term operation of the air conditioner discharges a large amount of heat, which deteriorates the heat dissipation condition of the heat dissipation system. If the fan, car radiator and other components fail, it will also affect the heat dissipation of the engine, which will cause the water temperature of the water tank to rise sharply in a short period of time until it boils.
The main method to prevent boiling is to carry out a comprehensive inspection of the car's heat dissipation system, such as checking whether the car radiator (such as aluminum car radiators) is running, whether the fan is normal, whether there is leakage in the water tank, and whether there is a lack of coolant, etc. If the water tank leaks, it needs to be repaired or replaced in time. If the water tank is short of liquid, it needs to be refilled in time. If the coolant becomes turbid and deteriorated, it needs to be replaced. The general coolant service life is two years. Car owners should also pay more attention to changes in the water temperature gauge in the dashboard. If the pointer of the water temperature gauge is too high, they should drive the car to an auto repair shop or 4S shop for inspection as soon as possible.
Here is a special reminder to car owners, do not use tap water to charge. Since many car owners use tap water as the engine cooling medium, this may be possible in the spring and autumn seasons, but in the hot summer, the engine's operating temperature will rise sharply under the scorching sun, and the boiling point of water is only 100°C, which is unable to satisfy the engine's heat dissipation, engine overheating will increase the friction between cylinder liners and pistons and reduce the lubricity of the oil. Over time, the engine will produce noise, power will decrease, and fuel consumption will increase. Moreover, water electrolysis will produce scale, which will gradually corrode the cylinder block, water tank and rubber parts, causing "scarred" engines, leading to engine failures and shortening the life of the engine.
