2003 Capacity 9.0L (9.5 qt)
COOLING SYSTEM: Use only phosphate-free coolant G 012 A8F A4, PURPLE COLORED. DO NOT INTERCHANGE OR MIX older G11(ZVW237 105),GREEN COLORED. This can result in serious damage to the engine.
However, it may be mixed with ZVW 237 G12, PINK COLORED.
Frost protection is required down to approximately -25°C (-13°F).
In countries with arctic climates, frost protection is required down to approximately -35°C (-31°F). The anti-freeze ratio must be a minimum of 40%, as otherwise frost protection is reduced.
The recommended mixture ratio is 50:50. If greater frost protection is required (very cold climates), the amount of G 012 A8F A4 can be increased, but only up to 60%.
Do not reduce the coolant concentration by adding water, even in warmer seasons and in warmer countries, as cooling effectiveness will be reduced.
