The 2019 Audi Q7 uses Volkswagen Group’s G13 long-life coolant. It’s a phosphate- and silicate-free formula designed for modern aluminum engines, typically pink or purple in color, and should be used as a 50/50 mix with distilled water unless you’re installing a pre-diluted OEM product. Use only coolant that meets VW/Audi specifications and avoid mixing with older formulas.
Understanding the exact coolant requirement helps owners prevent engine cooling problems, corrosion, and costly repairs. The following guide outlines the recommended coolant type, sourcing, and maintenance steps tailored to the 2019 Audi Q7.
Coolant type and specification
Key facts about the coolant your 2019 Audi Q7 requires and how it should be used:
- Type and formulation: G13 long-life coolant (organic acid technology) designed for VW/Audi engines with aluminum components.
- Specification: Must meet VW TL 774 F, the current VW/Audi standard for G13 coolants.
- Color and identification: Typically pink/purple; check the label to confirm it is G13.
- Mixing and dilution: Generally used as a 50/50 mix with distilled water, unless you purchase a pre-diluted 50/50 product from Audi/VW.
- System compatibility: Do not mix with G11, G12, or G12+ unless the cooling system has been flushed; if transitioning from a non-G13 coolant, a full flush is recommended.
- Where to buy: Use official Audi/VW-approved coolant or an equivalent that explicitly meets VW TL 774 F specification.
Accurate identification and sourcing of the correct coolant help ensure optimal cooling performance and engine longevity. When in doubt, consult a dealer or a qualified technician.
Maintenance and replacement guidance
Preparing for a coolant change or checking the system requires following best practices and documented procedures.
- Replacement guidance: Follow the maintenance schedule in the owner's manual or consult a dealer for the recommended interval; G13 is designed for long life but still requires periodic servicing.
- Replacing procedure: Drain the old coolant completely, flush the system if transitioning from a non-G13 coolant, then fill with a 50/50 mix of G13 coolant and distilled water. Ensure the level is correct after filling.
- Bleeding the system: Properly bleed the cooling system to remove air pockets to prevent hot spots or overheating; refer to the vehicle’s service manual for the exact bleed sequence.
- Safety and disposal: Wear protective gear when handling used coolant; dispose of used coolant at an authorized facility; never pour it down the drain.
- Where to have it done: Dealerships or independent shops with VW/Audi expertise, or a careful DIY approach with the right tools and knowledge.
Maintaining the correct coolant type and a properly bled, clean cooling system helps prevent overheating, corrosion, and expensive repairs down the line.
Summary
In short, the 2019 Audi Q7 requires G13 long-life coolant that meets VW TL 774 F. Use OEM Audi/VW coolant or a certified equivalent, and mix it as directed (typically 50/50 with distilled water). Do not mix with older formulas without a system flush, and follow the owner’s manual for replacement intervals and bleeding procedures. When in doubt, consult a dealer or qualified mechanic.
