Cooling system
The engine is water cooled. In the event of a high engine coolant temperature being indicated, check the coolant
level first.
Also check that the radiator grille behind the driver's seat is not clogged. See “Checking radiatorgrilles” on page 79.
The correct engine coolant level is important for the cooling system to function properly. Therefore, the engine
coolant level should be checked regularly. See warnings on the next page. The coolant must be visible when the filler
cap is removed.
Continuous coolant losses mean that there is a leak. In such a case, the cooling system should be checked by a
qualified technician. It is not sufficient to only top up the coolant. If the engine overheats, the coolant drops. Allow the
engine to cool before filling.
The cooling system must not be filled with salt water, this causes corrosion damage to the engine.
Change the coolant if it is discoloured or dirty. The cooling system must then be thoroughly flushed.
When draining the cooling system, both the taps must
be opened.
IMPORTANT INFORMATION:
WARNING:
WARNING:
Coolant filling
Coolant must be a mixture of 50 % antifreeze fluid
and 50 % soft water. Anticorrosion agent in the
coolant will be diluted if a reduced mixture is used.
A higher mixture can negatively influence the cooling
capacity. Salt water or water with a high lime content
can cause corrosion or deposits in the cooling system.
Do not open the cap quickly when the engine is hot,
first release the overpressure with the cap partially
slackened off. Risk of burns. Use protective gloves
and protective goggles.

The antifreeze fluid and coolant are hazardous to
health. Store them in marked containers that are
inaccessible to children and animals.
