Checking the coolant level
– Check the coolant level on the
reservoir.
The coolant should lie between the MIN
and MAXmarkings (36).
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 motor is hot, the radiator system is
pressurised. Only open the expansion
vessel (37) lid when the motor 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 motor does not contain any coolant.
For details on recommended concentrations and safety measures, refer to Chapter F.
