Antifreeze, also known as coolant, is an indispensable liquid in the vehicle cooling system. It not only prevents the engine from overheating, but also prevents the cooling system from freezing in low-temperature environments. There are many types of antifreeze on the market, and Volkswagen G12 and G13 are two common types. Many car owners have a question when faced with these two anti-freezing liquidscashoptionformegamillions: Can they be mixed?
1. Composition and function of antifreeze
Antifreeze mainly consists of water, ethylene glycol (or propylene glycol), anti-corrosion additives, etc. Ethylene glycol or propylene glycol is a key ingredient in lowering the freezing point of water and raising the boiling point, so that antifreeze does not freeze at low temperatures and does not boil at high temperatures. Anti-corrosion additives can reduce the corrosion of metals inside the cooling system and extend the service life of the cooling system.
2. Differences between Volkswagen G12 and G13 antifreeze
Although G12 and G13 are both popular brand antifreeze, their compositions and concentrations are different. G12 Antifreeze is a universal antifreeze that is suitable for cooling systems of a variety of vehicle models, while G13 is a long-lasting antifreeze with a longer service life and stronger corrosion resistance. The main difference in composition between the two anti-freezing liquids lies in the concentration of ethylene glycol. G13 has a higher ethylene glycol concentration, so it has stronger corrosion resistance.
3. Risks of mixing antifreeze
Due to the differences in the composition and concentration of G12 and G13, mixed use may pose certain risks. First of all, mixed use may cause changes in the freezing point and boiling point of the antifreeze, affecting the normal operation of the cooling system. Secondly, when different anti-corrosion additives are mixed, they may produce chemical reactions, reduce the anti-corrosion effect, and even accelerate metal corrosion. Finally, mixed use may affect the uniformity and stability of the antifreeze and increase the risk of cooling system failure.
4. Correct use of antifreeze
In order to ensure the normal operation of the cooling system and extend the service life, it is recommended that car owners use antifreeze correctly in the following ways:
Choose the antifreeze that suits your model and follow the automaker's recommendations. Regularly check the level and concentration of antifreeze, and add or replace it in time if necessary. Avoid mixing antifreeze of different brands and components. Clean and replace the cooling system regularly to keep the antifreeze clean and anti-corrosion effect.V. Conclusion
To sum up, although Volkswagen G12 and G13 antifreeze are similar in some aspects, due to differences in their compositions and concentrations, mixed use may bring certain risks. In order to ensure the normal operation of the cooling system and extend the service life, car owners are advised to follow the recommendations of the car manufacturer, choose the antifreeze suitable for their own model, and follow the correct use method.
Antifreeze type, composition concentration, suitable for model life, corrosion resistance, Volkswagen G12 water, ethylene glycol, and anti-corrosion additives are moderate for multiple models, General Volkswagen G13 water, ethylene glycol (higher concentration), and anti-corrosion additives are high, suitable for multiple models are longer and stronger
