Coolant, Draining And Filling: Filling
- The ignition is off.
Only Mix Distilled Water With Coolant Additives. Using Distilled Water Provides Optimum Corrosion Protection.
The water portion of the coolant influences the effectiveness of the coolant. Based on the contents, the country or even the region specific quality can be different. Use distilled water. For this reason, we recommend using distilled water when adding coolant or filling coolant for the first time.
Use only coolant additives listed in the Service 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 consequently to severe engine damage.
Coolant with the correct mixture ratio prevents freezing and corrosion damage and calcium deposits. The boiling point will be raised. The cooling system must be filled with coolant additive year-round.
Because of its high boiling point, the coolant contributes to engine reliability under heavy loads, particularly in countries with tropical climates.
The Refractometer:T10007A MUST be used to determine the freeze protection value.
Protection against frost must be assured down to approximately -25 °C (in arctic climatic countries down to approximately -36 °C). When stronger freeze protection is needed due to the climate, the freeze protection may be increased. But only up to -48 °C, otherwise the effectiveness of the coolant decreases.
The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. The frost protection must be at least -25 °C.
Read the freeze protection value on the scale for the coolant additive that has been added.
The temperature on the Refractometer:T10007A corresponds to the >>freezing point<<. At this temperature, ice crystals may begin to form in the coolant.
Do not reuse used coolant.
Only use water/coolant additive to lubricate the coolant hoses.
-- Close the drain plug -1-.
Ignore -item 2-.
-- Install the coolant hose on the engine oil cooler -arrow-.
-- Fill the coolant reservoir on the Cooling System Charge Kit:VAS6096 with twelve liters of premixed coolant with the proper mixture ratio.
