What is the pink fluid in a Volkswagen car?

[LaKingston]

Volkswagen car's pink fluid is antifreeze. Advantages of antifreeze are as follows: Anti-corrosion function: The engine and its cooling system are made of metal, including copper, iron, aluminum, steel, and solder. These metals will corrode and rust over time when exposed to water under high temperatures. Antifreeze not only prevents corrosion to the engine cooling system but also has anti-corrosion and rust removal functions. High boiling point of antifreeze: The boiling point of water is 100 degrees Celsius, while high-quality antifreeze coolant typically has a boiling point above 110 degrees Celsius. Thus, in summer, antifreeze coolant is less likely to boil over compared to water. Antifreeze prevents scaling: The most troublesome issue for drivers using water as a coolant is scaling. Scale adheres to the metal surfaces of the radiator and water jacket, reducing heat dissipation efficiency and being difficult to remove. High-quality antifreeze is made with distilled water and contains anti-scaling additives, which not only prevent scaling but also have descaling functions. Of course, if the radiator has thick scale buildup, it's best to thoroughly clean it with a radiator cleaner before adding antifreeze.

I've been driving my Volkswagen for almost five years now, and the first time I noticed pink fluid under the chassis, I was really nervous. Later, after asking a friend, I learned that it's the car's coolant, also known as antifreeze, and it plays a huge role! It prevents the engine from freezing in winter and overheating or boiling in summer. Volkswagens particularly like to use this pink type, such as the G13 formula, because the dye color is used to distinguish between different types. It's usually located in the coolant reservoir in the engine bay, and you should top it up promptly when the level is low. During regular maintenance, check it—if the color fades or becomes cloudy, it might be time for a change. I replace mine every two years to avoid any issues. Without this fluid, the engine could overheat and break down while driving—safety first! It's recommended that car owners regularly top up with dedicated coolant and avoid adding plain water, as it can corrode the system.

As someone who frequently works on Volkswagen vehicles, coolant issues are a common sight. That pink liquid is antifreeze coolant, essentially a mixture of ethylene glycol, with Volkswagen models using the G12 or G13 series, and the pink color primarily serves to indicate its non-corrosive nature. It resides within the cooling system, tasked with dissipating heat and preventing freezing. If your car is leaking pink fluid, immediately check the coolant reservoir—the transparent plastic container located at the lower left of the engine bay. A coolant level that's too low can cause overheating and engine damage. The inspection method is straightforward: after starting the car and allowing the engine to cool, open the reservoir cap to check the color and level. During maintenance, remember: don't substitute with plain water; use Volkswagen-certified coolant mixed with purified water. Typically, it should be replaced every two years or 50,000 kilometers to avoid leaks leading to major repairs.
