What brand of antifreeze does the Audi Q5 use?
2 Answers
Audi Q5 uses G13 antifreeze. Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent properties such as preventing freezing in winter, boiling in summer, and preventing scale and corrosion throughout the year. Composition of antifreeze: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances. Types of antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can antifreeze be mixed: The same brand of antifreeze must be used. Different brands of antifreeze may have different production formulas. If mixed, various additives may undergo chemical reactions, causing the additives to fail. How to choose antifreeze: The basic indicators of antifreeze are freezing point and boiling point. The market offers antifreeze with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region.
As a maintenance technician who has been working with Audi vehicles for years, I've encountered numerous coolant-related issues with Q5 models. The factory-installed coolant doesn't actually have a fixed commercial brand, but is specially formulated according to Volkswagen Group's VW TL 774-F standard (also known as G13 specification). This coolant's main performance characteristics include not freezing at -40°C and not boiling at 135°C, while also containing silicate corrosion inhibitors to protect aluminum engines. Although dealerships only label it as Audi-specific coolant, I've dismantled the packaging and found most are actually BASF's Glysantin series produced as OEM. One crucial reminder: when topping up, never randomly mix with other coolant brands, especially mixing silicate-based with organic acid types which can cause gelation. I recommend directly purchasing products with G13 certification labels, or reputable alternatives like Pentosin or Febi Bilstein. For regular maintenance, remember to check the freezing point and pH value every two years - immediate replacement is required if discoloration or cloudiness appears.
