6.2.3 Coolant
6.2.3.1
General
For fluid cooled engines the cooling fluid must be prepared by
admixing a cooling system protection agent to the fresh water and
should be checked within the specified maintenance intervals.
This prevents damage caused by corrosion, cavitation, freezing
and overheating.
6.2.3.2
Water quality
The correct quality of water is highly important when preparing
coolant. Clear and clean water within the boundaries of the fol-
lowing analysis values should generally be used.
Analysis values
pH-value at 20 °C (68 °F)
6.5 - 8.5
Chlorine-ion content
max. 100 mg/l
Sulphate ion content
max. 100 mg/l
Water hardness (ion content of
calcium and magnesium )
max. 3.56 mmol/l
max: 356 mg/l (ppm)
Germ degree:
max. 20 °dH
English degree:
max: 25 °eH
French degree:
max: 35.6 °fH
Bacteria, fungi, yeasts
not permitted
Information concerning the water quality can be obtained from the
waterworks.
If the fresh water analysis values are unknown, these must be
determined with the help of a water analysis.
If the values of the analysis deviate, the water must be treated
accordingly:
pH-value too low
- Adding of caustic lye of soda or caustic
potash solution.
Water hardness too
high
- Mix with soft, distilled or fully demineral-
ized water
Chlorides and/or sul-
phates too high
- Mix with distilled or fully demineralized
water
NOTICE!
Danger of engine damage!
–
Another analysis must be made after the fresh
water has been prepared.
