What kind of antifreeze should be added to the Bora?

Bora should be filled with the original factory-approved antifreeze. The following is an introduction to the function of antifreeze and how to replace car antifreeze: Function of antifreeze: The main function of antifreeze is to prevent the coolant from freezing and cracking the radiator or freezing the engine cylinder block or cover when the car is parked in cold winter; while in summer when the temperature is high, it can effectively prevent boiling and avoid the phenomenon of overheating. Antifreeze also has anti-corrosion function. How to replace car antifreeze: First, check the car to see if there are any signs of leakage, drain the remaining antifreeze, insert a rubber tube connected to a water pipe into the radiator filler port, turn on the faucet to let the water continuously flow through the engine cooling system, and after cleaning, add new antifreeze.
As a long-time Bora owner, I've always used the coolant recommended by Volkswagen, such as the G12 or G13 series, depending on the car's year. My car is a 2017 model, and the manual clearly states to use G13-compatible red coolant. I once tried a no-name brand, which ended up corroding the cooling system pipes, costing me thousands to repair. Coolant isn't just for winter antifreeze; it also prevents boiling in summer and protects the engine from rust. When buying, look for the Volkswagen certification mark, and don't mix different brands or colors, as this can cause crystallization and clog the radiator. Always wait for the car to cool down before topping up, and check the fluid level near the MAX line by opening the auxiliary tank cap. Too low a level can lead to overheating damage. Check it yourself twice a year, with pre-winter being a critical time. A single change lasts about two years, offering good value for money—don't skimp on quality to save a little.
I'm quite into car maintenance, and coolant is no trivial matter. For Volkswagens like the Bora, the OEM G-series, such as G12++ or G13, is the best fit, typically in purple or pink. Different formulations vary significantly—basic functions include preventing freezing at low temperatures, resisting boiling at high temperatures, and protecting against rust and bubbles. Compatibility is key. I've tried some third-party brands, like those from major manufacturers that are compatible with G13, which perform similarly but cost a bit less. However, inferior products contain fewer silicates, offering poor rust protection and causing long-term wear to the water pump and pipes. When topping up, ensure the level reaches the midpoint when the engine is cold, and avoid overfilling; mixing coolants can lead to sediment and engine damage. A replacement cycle of every two years is recommended. If the coolant feels gritty to the touch, replace it immediately to protect your car.
Safety first! As a veteran driver of a Bora, I recommend using Volkswagen's genuine antifreeze, such as G12 or G13. Using the wrong type or mixing different coolants can cause freezing and expansion, which may lead to radiator bursts in winter, resulting in costly repairs. My advice is to check the manual or consult a 4S shop to confirm the correct type to avoid accidents. When the fluid level is low, promptly top it up with the dedicated antifreeze—never use tap water as a substitute, as it accelerates corrosion. Regularly check the color of the overflow tank; if it appears cloudy or has excessive impurities, it indicates aging and requires a complete replacement. Always inspect the cooling system before driving to avoid breakdowns in cold areas.
