Antifreeze – the car's worst enemy.
Car maintenance, replacing antifreeze is one of the most critical maintenance items. You must value the antifreeze benefits of antifreeze, but there are some important facts about your engine cooling system that need to be taken seriously
Fact one: More than 50% of engine failures are caused by a failed cooling system. The main cause of cooling system failure is damage to components or reduced performance due to corrosion.
Fact 2: 7 out of 10 vehicles have a corroded cooling system, indicating that more than 70% of antifreeze is counterfeit.
Fact 3: It must be used all year round, in summer, the probability of engine failure is significantly higher than usual, most of which are caused by the high working temperature of the engine, a good antifreeze must have good high temperature resistance, but also have anti-corrosion, rust removal and other functions. Experts clearly pointed out that antifreeze must be used in summer, the boiling point of water is only 100 degrees Celsius, and the overheating of the engine will cause the water tank to "boil", the gas in the cylinder will expand, the air intake will be reduced, the power will decrease, the gap between the engine parts will be reduced, the lubricating oil will become thinner, and the friction between the engine parts will be intensified, and even irreparable damage will be caused such as "pulling the cylinder" and "holding the tile".
The boiling point of antifreeze is above 120 degrees Celsius, which can prevent the car from "boiling" in summer.
Therefore, antifreeze, which is essential for protecting the cooling system, is only the "basics" to prevent ice formation in winter, and it is the "real work" to protect engine parts from corrosion!
1. Pay attention to the freezing point of the product.
The lower the freezing point, the better the antifreeze effect of the product in an extremely low temperature environment. For example, the high-tech Mobil Antifreeze and Rust Fluid, which has a freezing point of -45, ensures that the engine can operate normally even in extremely cold weather.
Second, the comprehensive anti-rust and anti-corrosion function is the key.
The engine cooling system uses a variety of materials, including aluminum, copper, iron, steel, zinc, rubber, plastic, etc., with a design life of more than ten years, but many cars will have seepage, water leakage and other phenomena, all of which are caused by shoddy antifreeze, good antifreeze can play a comprehensive role in protecting all materials to prevent such phenomena from occurring.
In a nutshell, a good antifreeze needs to have two major elements: a low freezing point and excellent corrosion and rust resistance, so as to fully protect the cooling system and engine, not only to help your car survive the winter, but also to ensure that your car's engine runs smoothly for a long time.

G12 antifreeze: the boiling point is 106-107, the freezing point is -40, and the antifreeze used in different batches may also be different.
There are also those with g11.
You can't match it yourself, if you can match it yourself, it's also very troublesome, it's better to buy the finished product. Antifreeze is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, antifreeze has excellent properties such as antifreeze in winter, boiling in summer, waterproof scale and anti-corrosion throughout the year. At present, more than 95% of domestic and foreign water-based antifreeze uses ethylene glycol, and compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot be antifreeze. >>>More
Normally. The antifreeze can be replaced once every two years or about 30,000 or 40,000 kilometers. Intermediate supplements. Add the same color as you.
Aqueous antifreeze for general use:
Its function is to increase the boiling point of cooling water, cool the engine, prevent corrosion of the cooling system, prevent scaling of cooling water, clean the cooling system and prevent foaming. When the engine temperature is above 80 degrees Celsius, water vapor is generated from the steel walls. The heat transfer of these water vapors is relatively poor, and it will slowly form a bubble layer in the peripheral metal of the cylinder, so that the heat in the engine cannot be dissipated in time, and over time it will produce scale, corroding the cylinder pipeline, water tank and water pump. >>>More
Anti-corrosion function, antifreeze.
The boiling point is high. The boiling point of water is 100 °C, high quality antifreeze coolant. >>>More
