▶ OTHERS
In liquid-cooled engines, the coolant
must be conditioned and monitored,
otherwise the engine could be damaged
by:
• Corrosion
• Cavitation
• Freezing
• Overheating
▶ 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.
▶ WINTER OPERATION WITH
DIESEL FUEL
Special demands are placed on the cold
behavior (temperature limit value of the
filterability) for winter operation.
Suitable fuels are available at filling
stations in winter.
At low ambient temperatures paraffin
discharges can lead to blockages in the
fuel system and cause operating faults.
25
For engines with common rail injection,
the mixing of petroleum and adding of
extra low additives is not permissible.
