Engine coolant level check
Only proceed with the engine stopped and at low temperature, in
order to avoid the risk of burning.
Remove the pressurization cap from the expansion tank.
Check that the coolant in the expansion tank is above the
minimum level.
If necessary, top up the expansion tank with Fluids, as contained in
the REFILLING table. Do not fill the expansion tank to the brim.
When the engine is cold, make sure that the coolant level is a few
centimetres below the filling hole.
In the event of an externally located level indicator as regards the heat
exchangers, proceed with the top up operation by making sure that
the coolant does not overfill the internal volume of the exchanger in
order to allow the expansion of coolant volume during increases in
temperature.
Engine visual inspection
It is a good habit to execute, before engine start, a series of simple
checks that might represent a valid warranty to avoid inconveniences,
even serious, during engine running. Such checks are usually up to the
operators and to the equipment's users.
Level controls and checks of any eventual leakage from the fuel,
cooling and lubricating circuits.
Notify the maintenance if any inconvenience is detected of if any
filling is necessary.
After engine start and while engine is running, proceed with the
following checks and controls:
Check presence of any eventual leakage from the fuel, cooling and
lubricating circuits.
Verify absence of noise or unusual rattle during engine working.
Verify, using the equipment devices, the prescribed pressure
temperature and other parameters.
Visual check of fumes (colour of exhaust emissions)
Visual check of cooling liquid level, in the expansion tank.
If the refill operations occur frequently a diagnosis of
the cooling circuit is necessary.
CAUTION!
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.
