Helpful information
All engines from model year 2008 are filled with anti-freeze additive G 12 Plus Plus (purple color). Additive G 12 Plus Plus is mixed with the old antifreeze additives G 11 (green color), G 12 (Red color) and G 12 Plus (purple color).
G 12 Plus Plus as a life-extending additive is suitable for use in gray cast iron and aluminum engines and also optimally protects the engine against low temperatures, corrosion, limescale and overheating.
G 12 Plus Plus increases the boiling point and improves heat dissipation.
The proportion of coolant must be at least 40% for frost protection down to -25°C and must not exceed 60% for frost protection down to -40°C, otherwise the frost protection will be weakened again and, in addition, the cooling effect deteriorates.
The freezing point of the coolant must be at least -25°C (in countries with an arctic climate - not less than -35°С).
The anti-freeze additive G 12 Plus Plus prevents damage, limescale formation and, in addition, increases the boiling point. For this reason, the cooling system, regardless of the season, must be filled with a coolant based on a concentrate with anti-corrosion additives,
In countries with tropical climates and high engine loads, high boiling point coolant plays a significant role in ensuring reliable engine operation.
Do not add water to the coolant (thus reducing the proportion of concentrate) even in the warm season or in countries with a warm climate. The proportion of additive to the coolant must be at least 40%.
Checking the coolant level, topping up if necessary
The coolant level in the expansion tank should be checked when the engine is cold.
Recommended coolant level for inspection service:
- The coolant level must be above the Min mark (arrow).
- If the coolant level is below normal, add the missing amount, mixing in the appropriate proportions.
If there is a decrease in the amount of coolant, which cannot be due to its use, the cause must be determined and eliminated.
Mixing ratio
Frost protection yes | Antifreeze additive G12 Plus Plus | Water |
-25°C | about 40% | about 60% |
-35°C | about 50% | about 50% |
