Checking the coolant level

The coolant level in the expansion tank must be between the two marks «Max» and «Min» (pic. 12).

The expansion tank is made of white plastic and has a blue cap.

Check the level and open the plug of the expansion tank to add fluid only on a cold engine. If the engine is hot, allow it to cool before removing the expansion tank cap to avoid splashing hot fluid, as the expansion tank is pressurized when the engine is running and warm. In the absence of a special coolant, it is allowed to use clean «soft» (e.g. rain) water, but its use increases the freezing point, increases corrosion and scale formation. The presence of water in the expansion tank at negative temperatures is not allowed. In addition, the use of sea water, hard water, and alkali for water softening is unacceptable.
