Key points of engine coolant replacement,HS code-based tariff calculations one article to solve the role of engine coolant is indispensable in automobile operation. It can effectively control the engine temperature, avoid overheating, and ensure the normal operation of the engine. However, it is important to replace the coolant frequently. If it is not replaced for a long time, it will affect the life of the engine and even cause serious damage. This article will introduce the key points of engine coolant replacement to ensure that your vehicle remains in the best condition for a long time.The role of coolant in the operation of the car engine produces a large amount of heat. If it is not controlled by a cooling system, the engine will overheat. In the state of overheating, the engine is prone to failure or even damage. At this time, the coolant is particularly important. Engine coolant can help lower the engine temperature and avoid overheating. At the same time, it can play the role of lubrication and anti-corrosion to protect the inside of the engine from corrosion. In a cold environment, the coolant can also prevent freezing and ensure that the engine can work normally under any conditions. The time interval for replacing the coolant Although the life of the coolant will vary depending on the car model and the usage environment, generally speaking, 6 months to 2 years is the recommended time to replace the coolant. Before replacing, it is recommended that you check the car user manual or contact the manufacturer for specific replacement suggestions.Precautions for coolant replacement. Before replacing the engine coolant, make sure that the engine has been completely cooled. Because the coolant will produce high pressure at high temperatures, if the engine is still in a high temperature state, it may cause serious burns. When replacing the coolant, the vehicle needs to be parked on a flat ground. If the vehicle is parked on a slope or potholed road, the coolant may not be completely discharged, affecting the replacement effect. When checking and replacing the coolant, you need to turn off the engine and completely cool the engine, and then open the water outlet to release the old coolant. If the old coolant has sediment or is mixed with other substances, it is necessary to clean up the parts inside the engine first to avoid the old sediment from polluting the new coolant. When adding a new coolant, you need to dilute the new coolant in proportion before adding it.When adding, avoid pouring coolant directly, and use a special injector to avoid fluctuation and waste. To sum up, the engine coolant of a car is of great significance to the normal operation comfort and safety of the vehicle. Be sure to add it according to the instructions for use of the car, and replace the coolant regularly to ensure that our car engine runs normally and even extend the life of the car. Therefore, every time the car has driven a certain mileage, the owner should regularly check and replace the coolant. Operating according to the above points can better protect the engine and extend the service life of the car.
