3.6. Individual Operations of Maintenance
3.6.3. Engine cooling liquid level check
• Let cooling liquid cool down to less than 50 °C (120 °F).
• You can read off the level of coolant on the expansion tank
display. The water level must be between the top (FULL) and
bottom (LOW) marks.
• Top up coolant as required.
Note:
The total amount of engine coolant is 1.2 l (0.3 US gal).
Dismantle the filling plug only when the temperature of
engine cooling liquid falls to less than 50 °C (120 °F). If
you open it at higher temperatures, you risk scalding by
steam or by cooling liquid due to the inner overpressure.
The level must not fall below the level indicator eyesight.
Refill only cooling liquids containing the frost-resistant
agents on the identical basis, according to chapter 3.2.3.
Do not add additives eliminating untightness of the
cooling system to the engine cooling liquid!
Do not refill cold cooling liquid into hot engine. Engine
castings might get damaged.
In case of larger losses, find the location of cooling sys-
tem leaks and repair the cause.
