The useful life of this coolant is three years.Ĭarboxylate and ethylene glycol are the main components of the red or pink G12 coolant. G11 coolant is often used in automobiles made before 1996, although due to its poor heat transfer quality, some vehicles made up to 2016 may also use it. What are the three’s distinctions then? G11 is a silicate base with inorganic additions that is either blue or green. G11, G12, and G13 are the three different varieties of antifreeze. Propylene glycol, often known as ethylene glycol, and additional ingredients make up engine coolant. The primary distinction is that glycerin, not glycol, is used in the manufacturing process. The G13 is colored purple or violet and has the same superb cooling and antifreeze performance as the G12++. Regular store-bought antifreeze frequently contains compounds that can damage gaskets and other system components. What sort of antifreeze do you put in your Volkswagen then? It is strongly advised that you only use antifreeze that has been approved by Audi/VW under G13 or G12. This will eventually result in significant mechanical issues. The radiator core will begin to accumulate deposits, which will impede the flow of coolant. You won’t be able to observe the damage occurring internally. Bulging coolant lines and white, calcified residue pouring out from under the hose clamps will make this clear. Additionally, parts of the cooling system made of metal, rubber, and plastic might become corroded by poor quality coolant. Your VW’s coolant system will respond negatively to inferior coolant. Never fill your Volkswagen with regular store-bought coolant, especially if it contains ethylene glycol, which will interfere with the system. Look for the recombined coolant type on your expansion tank as well. You should only use G11 or G12 authorized anti-phosphate, anti-amine, and anti-phosphorous coolant in your Volkswagen, depending on what the owner’s manual instructs you to use. Which type of coolant should I use in my Volkswagen? For the best engine health, make sure you maintain the proper coolant concentration. Use only distilled or bottled water for this.Ĭheck the pH of your coolant frequently. You must diluted it with distilled water to a 50/50 concentration before using it in your engine. If you want to change colors, properly flush the coolant system first before applying the new color.Ĭoncentrated Volkswagen coolant is available. If you’re topping off, choose the same color that your car already has. The color of Volkswagen coolant is always pink or purple. Both the owner’s manual and the expansion tank should be stamped with the precise type that your specific model employs. Volkswagen only utilizes antifreeze that is Audi/VW G13 or G12 certified.
