MAINTENANCE
COOLING SYSTEM
1. Check the fan belt tension regu-
larly. Adjust, If required.
. Check the coolant level in the ra-
diator fins always clean.
. Replace the radiator cap with a
genuine cap only, if required.
4. Do not remove the thermostat
but replace with a new one, if re-
quired.
5. Do not change the radiator water
often.
► WINTER OPERATION WITH DIE-
SEL FUEL
Special demands are placed on the
cold behaviour (temperature limit val-
ue of the filtrability) for winter oper-
ation. Suitable fuels are available at
filling stations in winter.
For engines with common
rail injection, the mixing of
petroleum and adding of ex-
tra low additives is not per-
missible.
•
IMPORTANT
At low ambient temperatures paraf-
fin discharges can lead to blockages
in the fuel system and cause operat-
ing faults. Below 0 °C ambient tem-
perature use winter diesel (down to
-0 °C) (filling stations provide this
in good time before the cold season
starts).
Special diesel fuels can be used
for arctic climates to -44 °C.
