10.7 Checking the coolant level
– Open the cover lock and turn it to the right
– Remove the cover
– Check the coolant level on the
reservoir.
The coolant should lie between the
MIN and MAX markings (26).
M
If the coolant is below the MIN
marking, this indicates possible
leakage in the radiator system. The
truck must only be used once the
cause has been removed.
F
If the engine is hot, the radiator
system is pressurised. Only open
the expansion vessel (27) lid when
the engine has cooled down.
When topping up, add a premixed water and antifreeze solution in equal quantities
into the existing solution.
It should be possible to empty the system by opening the drain taps in the radiator
and on the side of the cylinder block. The drain plugs may be made of brass. When
draining, remove the expansion vessel lid and lay it on the driver's seat as an indicator
that the engine does not contain any coolant.
For details on recommended concentrations and safety measures, refer to Chapter F.
10.8 Checking the coolant concentration
F
Do not open the radiator lid when
the engine is hot.
To prevent the build up of lime as
well as front and corrosion
damage, and to raise the boiling
point temperature, the cooling
circuit must be filled each year with
a mixture of water and anti-freeze
with anti-corrosion additives.
– If there is insufficient anti-freeze,
drain the coolant and add anti-
freeze to the reservoir (28) until
you obtain the correct proportion
in the mixture.
