16. Change intermediate axle oil filter (6x4

vehicles)

40658

Using tool 99360314, remove the oil filter (1) from the
differential of the intermediate axle.
Before fitting the new oil filter on, moisten the seal with
lubricating oil.
Screw the filter on by hand until it is in contact with the
mounting and then tighten it by 3/4 of a turn.

Check pollen filters

Every six months
Check the state of clogging of the pollen filter (1).

It is reached by lifting the front radiator cowling and
unscrewing the six supporting screws.

Excessive clogging of the pollen filters can cause a
reduction in the flow rate of air into the cab and
therefore less ventilation.
This will be highlighted especially by a significant
reduction in the efficiency of the windscreen
defrosting function.

Wash radiator grille

Lift the cab radiator cowling and carefully clean the radiator
grille.

T2 SERVICE

Check percentage of antifreeze in the
engine coolant

The plug (1) must never be taken out for any reason
whatsoever.
With the engine warm, the cooling system is in
overpressure, therefore take care when taking off
the cap (2).

72588

Take off the cap (2) and draw off a sample of the coolant
from the expansion tank (3) with the densimeter 99395858.

Depending on the temperature of the liquid, check the
percentage of antifreeze in the liquid on the scale of the
instrument. The percentage has to be higher than 40% and
must not exceed 50%.

If necessary, restore the percentage of antifreeze, bearing in
mind that the liquid needs to be replaced every 2 years.

For vehicles fitted with an additional heater, the
percentage of antifreeze must never exceed 50%.

To renew the blow-by filter, remove the screws and the
cover, withdraw the filter (3) along with its gaskets.
Carefully clean the seating of the filter and the cover.
Fit a new filter with new gaskets. Refit the cover and tighten
the fixing screws (2) to the prescribed torque.
The filter only operates in one flow direction and therefore
must be installed with the reinforcing bars visible as shown
in the figure.

Change engine coolant

Carry out the procedure described under the relevant
subheading of the ”ENGINE” section.

24. Renewal of the blow-by filter

Changing the clutch fluid and bleeding the
hydraulic clutch control system
(versions with ZF 16S 181/221 gearbox
only)

72568

Drain off the clutch control fluid and change it (see Fluids
table in GENERAL section).

The clutch fluid is poisonous and corrosive: if you
accidentally come into contact with it, wash
immediately with water and a neutral soap.

Figure 67

Figure 68

After changing the fluid, bleed the hydraulic clutch control
system.
Use the air bleeding tool 99306010 as follows:

- charge reservoir (5) with compressed air;

- fill reservoir (4) with Tutela TRUCK DOT SPECIAL fluid

- replace the cap (

⇒) of the clutch fluid reservoir with one

of the caps supplied with the tool 99306010 and
connect the pipe to the cap.

- Attach a plastic tube to the bleed screw (2) on the slave

cylinder (1) and immerse the opposite end of the tube
in a container containing Tutela TRUCK DOT SPECIAL
fluid, unscrew the bleed screw (1) by one full turn, open
the valve (2) (see Figure 52) until a pressure reading of
1 to 1.2 bar is obtained on the pressure gauge (3);

- when the clutch fluid flowing through the tube is uniform

and free of air bubbles, close the bleed screw and
discharge the air from the reservoir (5) through valve (6).

Figure 69

Whenever the clutch fluid is changed, it will also be
necessary to bleed the clutch master cylinder by
loosening the fitting (1, Figure 68) before bleeding
the clutch servo.
