Maintenance: Freshwater system
Freshwater system. Flushing
The system should be flushed before changing cool-
ant to avoid inferior cooling performance due to depos-
its in the cooling system.
IMPORTANT! Certain parts of the system are
made of light alloy. Chemical additives must
therefore not be used when cleaning.
1. Drain the coolant as described earlier.
2. Insert a hose into the filler opening in the heat ex-
changer and flush with fresh water.
3. Flush until the water running out of the drainage
points is clean.
4. Close all drainage points when all the fresh water
has run out.
5. Fill with coolant as described on the previous
page.
