Winter Operation with Diesel Fuel
The winter operation of the diesel engine is subject to different demands (filterability) than the operation
during other seasons.
Special demands are placed on the cold behaviour (temperature limit value of the filtrability) for winter
operation. Suitable fuels are available at filling stations in winter.
Important: For engines with common rail injection, the mixing of petroleum and adding of
extra low additives is not permissible.
At low ambient temperatures paraf- fin discharges can lead to blockages in the fuel system and cause
operating faults. Below 0 °C ambient temperature use winter diesel (down to -20 °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.
Cooling System
1. Check the fan belt tension regularly. Adjust, If required.
2. Check the coolant level in the radiator fins always clean.
3. Replace the radiator cap with a genuine cap only, if required.
4. Do not remove the thermostat but replace with a new one, if required.
5. Do not change the radiator water often.
Caution: Never operate the engine without coolant, even for a short time!
In liquid-cooled engines, the coolant must be conditioned and monitored, otherwise the engine could be
damaged by:
Corrosion
Cavitation
Freezing
Overheating
