Check engine coolant level
Only proceed when the engine is not turning, and is at low
temperature, so as not to run the risk of burns.
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 a mixture of 50%
water and PARAFLU 11, as contained in the section FLUIDS. Do
not fill the expansion tank to the brim.
When the engine is cold, make sure that the coolant in the
expansion tank 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.
Check the cleanliness of the heat exchanger
(radiator)
Check that the air intake surfaces of the radiators are free of impurities
(dust, mud, straw etc.).
Clean them if necessary using compressed air or steam.
If frequent coolant top-ups are necessary, the cooling
circuit must be diagnosed.
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.
When using compressed air, it is required to use
suitable personal protections for hands, face and eyes.
The requirements can be found in the ACCIDENT
PREVENTION paragraph.
