NOTE:
- Only use coolant additive G 12 in accordance with TL VW 774 D. Identification color: red
- Under no circumstances must G 12 be mixed with other coolant additives!
- If the fluid in expansion tank is brown, G 12 has been mixed with another coolant. In this case the coolant must be changed.
- G 12 and coolant additives marked In accordance with TL VW 774 D prevent frost and corrosion damage, scaling and also raise the boiling point of coolant. For this reason the system must be filled all year round with frost and corrosion protection additives.
- Because of its high boiling point, the coolant improves engine reliability under heavy loads, particularly in countries with tropical climates.
- Protection against frost must be assured to approx. -25 ° C (in arctic climatic countries to approx. -35 ° C).
- The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. The anti-freeze ratio must be at least 40%.
- If for climatic reasons a higher frost protection is required, the amount of G 12 can be increased, but only up to 60% (frost protection to about -40 ° C), as otherwise frost protection is reduced again and cooling effectiveness is also reduced.
- Refractometer T10007 is recommended for determining the current density of the anti-freeze.
- If radiator, heat exchanger, cylinder head or cylinder head gasket are replaced, do not reuse old coolant.
Recommended mixture ratios:
| Anti-freeze to | Anti-freeze proportion | G 12 * See note | Water * See note2) |
| -25 ° C -35 ° C | 40% 50% | 3.7 l 4.6 l | 5.5 l 4.6 l |
* The quantity of coolant can vary in accordance with the equipment fitted to the vehicle.
* Only use clean drinking water.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
