FILLING
Note. The cooling system is filled year year-round with a mixture of water and coolant additive. Mixture ratio COOLING SYSTEM, DRAINING AND FILLING . Only use coolant according to maintanence information. Other coolant additives may above all reduce the corrosion protection effect significantly. The damage resulting from this may lead to loss of coolant and consequent severe engine damage. Coolant with the correct mixture ratio COOLING SYSTEM, DRAINING AND FILLING prevents freezing and corrosion damage and calcium deposits. They also raise the boiling point. The cooling system must be filled with coolant additive year-round. 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 down to approximately -25 °C (-77 °F) (in arctic climatic countries down to approximately -35 °C (-95 °F)). The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. Coolant additive portion must be at least 40%. When stronger freeze protection is needed due to the climate, the portion of coolant additive can be increased up to 60% (freeze protection down to approximately -40 °C (-104 °F)). Otherwise the freeze protection and cooling effect are reduced. Only use clean drinking water for mixing coolant. If radiator, heat exchanger, cylinder head or head seal or cylinder block were replaced, do not reuse used coolant. Dirty coolant may not be used again. Use the T10007 to check the freeze protection in the cooling system.
COOLANT MIXTURE RATIO
- Coolant additive (40%) and water (60%) for freeze protection down to -25 °C (-77 °F) (-77 °F)
- Coolant additive (50%) and water (50%) for freeze protection down to -35 °C (-95 °F)
- Coolant additive (60%) and water (40%) for freeze protection down to -40 °C (-104 °F)
