Antifreeze is an important part of an automotive engine's cooling system, which not only protects the engine from operating at low temperatures, but also prevents corrosion and fouling of the tank and pipes. Therefore, it is very important to change the antifreeze regularly for the proper functioning of the car. Two common scenarios for antifreeze replacement are described below.
The first case is a new car. After buying a new car, the replacement time and mileage of the antifreeze will generally be indicated in the car manual, and it is recommended to replace the antifreeze once in about 5000 kilometers or 1 year for a new car. If the replacement time is not indicated in the vehicle instruction manual, it is recommended to choose antifreeze according to the driving environment and temperature of the car, and regularly check the liquid level height and freezing point of the antifreeze to prevent the antifreeze from expiring and deteriorating, which will affect the normal operation of the cooling system.
The second scenario is when the vehicle is parked for a long time. Long-term parking of the vehicle will cause the antifreeze to deteriorate in the cooling system and lose its functions such as antifreeze and anti-corrosion. Therefore, before the vehicle is parked for a long time, the antifreeze should be completely drained and the cooling system should be cleaned to avoid damage to the engine caused by the deterioration of the antifreeze. After the vehicle is parked for a long time, it is recommended to replace the antifreeze before using it again to ensure its normal function.
The choice of antifreeze is also very important. Antifreeze should be chosen according to the recommendations of the vehicle manufacturer, and in general, the replacement time and mileage of antifreeze will be indicated in the car instruction manual. If you notice that the color of the antifreeze has become cloudy or the liquid level has dropped, it means that the antifreeze has deteriorated and needs to be replaced immediately. At the same time, antifreeze can not be mixed, it is recommended to use the same brand of antifreeze all the time, and pay attention to the freezing point of antifreeze, should choose antifreeze with a freezing point more than 10 times lower than the minimum temperature in the area.
When changing antifreeze, there are a few things to keep in mind:
1.The vehicle should be cooled down before changing the antifreeze so as not to burn yourself.
2.When replacing antifreeze, the antifreeze should be completely drained from the tank and lines and the cooling system should be flushed with clean water.
3.The tank should be filled with clean water before new antifreeze is filled, then drained before new antifreeze is filled.
4.When injecting antifreeze, it should be injected slowly to avoid bubbles that affect the cooling effect.
5.When injecting antifreeze, care should be taken not to add too much or too little, just add between the highest and lowest water levels.
The above are the two common situations about antifreeze replacement, I hope you can pay attention to the situation of vehicle antifreeze in time, and replace antifreeze regularly to ensure the normal operation of the vehicle.
