10.3.5 Cooling system
The radiator has a protective grille that also serves as a prefilter for the
cooling air. This filter and the radiator must
be cleaned regularly with
compressed air to prevent the engine from overheating. Cleaning with
water could block the radiator fins. Using a high-pressure hose could
bend the fins.
The protective grille can be removed by undoing the retaining clips (Fig.
10.3.5-1).
When replacing the grille, make sure the gasket lips are pressed against
the radiator. Damaged gaskets must be replaced to prevent grass and
dirt particles from clogging the radiator.
The machine is fitted with a transparent water expansion tank. This does
not prevent overheating, but ensures that the overheated water can con-
dense and be returned to the system. The fluid level in the expansion
tank should be checked daily.
Refill the radiator if the coolant circuit is empty. To do so:
•
Undo and remove the radiator cover (Fig.10.3.5-2/1)
•
Fill the radiator to the lip with coolant (Fig.10.3.5-2/2), then refit the
cover
•
Open the expansion tank (Fig. 10.3.5-2/4)
.
•
Fill the tank to the MIN/MAX mark
•
Close the tank cap (Fig.10.3.5-2/3)
(The cap has ventilation holes because this is a pressureless
equalisation system)
•
Start the engine and check the tank level
•
Add coolant if the level is below the MIN/MAX mark
CAUTION
-
All covers must be closed when the engine is started.
-
Do not open and/or fill the tank with the engine running.
-
To avoid the risk of burns, do not open the radiator until it
has cooled down
.
-
THE TANK COULD BE PRESSURISED.
