I remembered to change the engine oil, but didn’t remember to add antifreeze. The car mechanic said: No wonder your car has so many problems!

There are three liquids in the car. I believe every car owner is very clear about them. They are engine oil, antifreeze and glass water. These three liquids have different functions. Relatively speaking, most car owners are more Paying attention to engine oil will affect the life of the engine after all. But antifreeze has been ignored. In fact, antifreeze plays a big role in the engine. The function of antifreeze is to balance the temperature and avoid damage caused by overheating of the engine. The normal operation of the engine is inseparable from antifreeze. Therefore, antifreeze is not less effective than engine oil. The reason that many people ignore is that the service life of antifreeze is relatively long. This is the main reason. Generally speaking, under normal vehicle use, the service life of antifreeze is 3-4 years, or it may be 2 years. How long or longer it takes depends mainly on the environment in which the car is used and the mileage. You can check whether the antifreeze needs to be replaced or added in about 3 years. Of course, when the vehicle is being maintained, the 4S store will also check the antifreeze for you at a similar time or mileage. However, most 4S stores will basically tell you that they need to be added or replaced every two years. I believe everyone knows why. So if it is only 2 years old, under normal circumstances, there is no need to add or replace antifreeze. Antifreeze, like engine oil, also has several different functions. Currently, antifreeze comes in red, blue, green and other colors. This is because antifreeze of different colors has different ingredients, so the effects are also different. Similarly, if it is better, it will naturally last longer and the effect will be relatively better. But you need to remember that these different colors of antifreeze cannot be mixed because they have different components. If they are mixed, they may cause damage to the engine. Therefore, if you need to replace the antifreeze, you need to clean the original one first and then add a new one, or you should not change the type and use the original antifreeze. In addition, many car owners will use water instead of antifreeze. Although this is possible, the effect is definitely not as good as antifreeze, and the protection effect on the engine is relatively low, so I still don’t recommend it.
