In car maintenance, the replacement of antifreeze is a very important link. Antifreeze, as the name suggests, is primarily designed to prevent the car's cooling system from freezing during the cold winter months. So, for the majority of car owners, how often is it best to change the car antifreeze? This article will analyze the SUV ranking network (www.).270top.com) different types of antifreeze and their service life, to answer this question for everyone.
We need to understand the types of antifreeze. There are two main types of antifreeze on the market: long-lasting and regular. The replacement cycle of long-lasting antifreeze is usually long, which can reach 5-10 years or more than 200,000 kilometers; The replacement cycle of ordinary antifreeze is shorter, generally 2-4 years or about 60,000 kilometers.
So why do different types of antifreeze have different lifespans? This mainly depends on the composition of the antifreeze and the manufacturing process. The long-lasting antifreeze uses high-quality organic acids and anti-corrosion agents, which have good chemical stability and are not easy to produce chemical reactions and deterioration; Ordinary antifreeze uses inorganic acids and additives, which have relatively poor chemical stability and are prone to chemical reaction and deterioration.
In addition to the type of antifreeze, the environment and driving conditions of the car will also affect the lifespan of the antifreeze. For example, when a car is used in cold regions, the freezing point of the antifreeze decreases, resulting in a decrease in the concentration and performance of the antifreeze; And when using a car in a high-temperature area, the antifreeze may be lost by evaporation, which will also affect its service life.
In addition, car owners also need to pay attention to the following points when replacing antifreeze: first, choose the original antifreeze of regular brand and reliable quality, and avoid using inferior products; Secondly, when replacing antifreeze, it is necessary to check whether there is leakage in the cooling system, and if there is leakage, it should be repaired in time; Finally, SUV Rankings.com (www.270top.com) After replacing the antifreeze, the engine needs to be started and run for a period of time to allow the new antifreeze to fully circulate and perform its role.
In short, the replacement cycle of car antifreeze is not static, and car owners need to determine the best replacement cycle according to the actual situation of their vehicle and the type and service life of antifreeze. Only in this way can you ensure the proper operation of the car's cooling system and the service life of the engine, so that your car is always in top condition.
