Why the right coolant is so important

During operation, the engine generates enormous temperatures. Without coolant, it would simply overheat. At the same time, the fluid protects against frost in winter, prevents limescale deposits in the radiator and lines, and prevents corrosion.

With the G12evo you are on the safe side:

  • Frost protection down to -35 °C - no risk of frost damage in winter
  • Heat protection up to 135 °C - even in traffic jams or high outside temperatures, the engine remains protected
  • Corrosion protection - special inhibitors form a protective film over all metal parts in the cooling system
  • Limescale protection - Deposits caused by hard water are avoided
  • Cavitation protection - protects against micro-damage caused by pressure fluctuations in the cooling system
  • Optimal material compatibility - adapted to metals, rubber and plastics in the VW cooling system

Technical delivery conditions (TL 774-L)

The VW coolant G12evo meets the strict Technical delivery conditions (TL 774-L)These specifications precisely define the physical, chemical, and technical properties a coolant must have—from ingredients to mixing ratios and material compatibility.

Volkswagen thus goes beyond general ISO standards. For you, this means absolute certainty that the product is tailored to your vehicle and will function reliably under all conditions.


How do defects occur?

Cooling system defects often arise from incorrect or inferior coolant, incorrect mixture, or insufficient fluid. Typical problems include:

  • Freezing due to insufficient antifreeze → Engine block or cylinder head can crack
  • Overheating due to incorrect mixture → Engine boils over, hoses burst
  • Limescale deposits → get stuck in cooling channels and block heat dissipation
  • corrosion → damages metals in the cooling system, leads to leaks
  • Cavitation → small gas bubbles cause micro-damage in metal parts

The consequences range from loss of power to high repair costs and even total engine failure.


What you should pay attention to as a customer

  • Maintain mixing ratio: at least 40%, maximum 55% coolant content

What happens if I drive with too little coolant?
The engine can overheat, causing expensive damage. There's also the risk of freezing in winter, which can damage the engine block.

Can I refill the coolant myself?
