Coolant refilling
For the initial engine start-up and in the cases in which the refilling of
the cooling circuit is required with a considerable quantity of coolant,
proceed as follows:
Refill the engine and the exchanger until the exchanger is
completely filled.
With the coolant filler plug open, start the engine and let it idle for
approx. 1 minute. This helps to completely bleed the air contained
in the cooling circuit.
Stop the engine and then top up with coolant if necessary.
Refuelling
Use only diesel oil in accordance with EN 590 standard normally
commercially available. Fuel additives are not recommended.
Use of additives can limit the guarantee performance offered for the
vehicle.
Diesel oil for low temperatures
At low temperatures the degree of fluidity of the diesel can become
low due to the separation of the paraffin resulting in the filters
becoming clogged.
Standard EN590 defines different diesel classes, identifying the
characteristics of those most suitable for use at low ambient
temperatures.
It is entirely the responsibility of the oil companies to comply with the
regulations regarding the distribution of fuels suitable for the climatic
and geographical conditions of the various countries.
The failure to observe the aforesaid procedure does not
guarantee the presence of the correct quantity of
coolant in the engine.
ATTENTION!
When the engine is hot, pressure builds up in the
cooling circuits which may eject hot liquid violently,
resulting in a risk of burns. Open the filler cap of the
coolant tank only if necessary and only when the
engine is cold.
ATTENTION!
Pay maximum attention when refuelling, making sure
that solid or liquid pollutants do not enter the tank;
please remember that smoking is prohibited while
refuelling. The couplings of the fuel circuit under high
pressure must not be loosened under any
circumstances.
