Take out the oil level dipstick (1).
From underneath the vehicle, remove the soundproofing
guard.
Unscrew the plug (3) from the oil sump and drain the engine
oil off into a specific container.
Screw the plug back on under the sump and tighten it to the
required torque.
Fill in with the prescribed oil quantity and quality (see the
CAPACITIES table in the GENERAL INFORMATION
section) from the tie rod cover pipe union (2).

Drain the oil as described in point 4. “Changing engine oil.”

Remove the oil filter (1) with tool 99360314 (2).

Before refitting the new cartridges, moisten the seal
with engine oil.

Screw the oil filters (1) on by hand to bring them into contact
with the mount and then tighten by 3/4 of a turn to the
prescribed torque and proceed as described in point 4.
“Changing engine oil.”

indicator

- Check the state of the filter (3) with the clogging

indicator (1).
If the red zone appears it is necessary to change it as
described in the T5 service.

19. Change or clean hydraulic steering system

filter

1-2. Check miscellaneous drive belts

Before taking off the cover (1), thoroughly clean the tank.

This will prevent foreign impurities from coming into contact
with the oil of the hydraulic system.

Take the cover (1) off the tank and take out the oil filter (3).

Remove the coupling device (2) from the oil filter (3) and
replace the filter.

Take off the plug (1) (after unhooking the transmitter) of the
hydraulic power steering tank and check that with the engine
running and the wheels travelling in a straight line, the oil level
reaches the top reference mark on the dipstick.

With the engine stationary and wheels in a straight line, the
oil level has to exceed the top reference mark of the dipstick
by 1 or 2 cm; if necessary, top up the level by taking off the
cover (1).

Visually check that the belts (1-2) are neither worn nor
deteriorated; if they are, change them as described in the M2
service.

22. Check state of engine blow-by filter

through clogging indicator.

17. Change pre-filter

Figure 8

85497

When replacing the cartridge, it must not have been
pre-filled. This is to prevent impurities getting into
circulation that could damage the injector/pump
system components. Bleed the air from the fuel
circuit as described on the previous pages.

Unscrew the pre-filter (1) and replace it.
Before refitting the new cartridge, moisten the seal with
diesel or engine oil. Screw the cartridge on by hand until it
is in contact with the mounting and then tighten by 3/4 of a
turn to the required tightening torque.

17. Change fuel filter

85498

Remove the fuel filter (1) with tool 99360314.
Before refitting the new cartridge, moisten the seal with
diesel or engine oil.
Screw the new one on by hand, taking care to check that the
rubber seal and the mating surface are clean and in a perfect
state of repair. Screw the cartridge on by hand until it is in
contact with the mounting and then tighten by 3/4 of a turn
to the required tightening torque.

Bleed the air from the supply system as described in the
following paragraph.

Bleeding air from the fuel circuit

- Open the bleed screws, connecting them with tubes to

run off the bled fluid into suitable containers to prevent
dirtiness:
1 = located on the pre-filter mount (on the chassis

frame);

3 = located on the filter mount (on the engine);
4 = located on the front of the cylinder head.

Figure 12

- Work the hand pump (2) on the pre-filter till you see fuel

with no air in it coming out of the bleed screw (1)
(retighten the screw when the operation is over).
Keep on pumping until you see fuel with no air in it come
out of the bleed screw (3) on the filter as well (then
retighten the screw) and from the screw (4) on the front
of the cylinder head (retighten the screw when the
operation is over) and tighten them to the required
torque.

The circuit has now been bled. Start up the engine and run
it for a few minutes at idling speed to get rid of all remaining
air.

Never let the fuel soil the drive belt: alternator,
pump, water, etc.

85501

13. Change pneumatic system drier filter

Discharge the pressure from the compressed air system.
With the right tool, remove the drier filter (1) from its
mounting and fit the new part.
Screw on by hand until there is contact with the mounting
and then tighten by 3/4 of a turn to the required torque.

If on removal you find there is too much oil in the
drier or in the intake pipe, check the conditions of
the compressed air as described under the relevant
heading.

85500

Check the level of the clutch fluid. Top it up if it is too low
(see the FLUIDS table in the GENERAL section).

Check clutch fluid level (vehicles with ZF 16
S 181/221 gearbox only)

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

The M2 service comprises the operations of the M1
service plus the ones listed here.

M2 SERVICE

Change variable geometry turbocharger
(VGT) valve air filter

85502

Using a suitable tool, unscrew the filter (1) and replace it.
Before fitting the new cartridge, moisten the seal with diesel
or engine oil. Screw it on by hand until it is in contact with
the mounting and then tighten by 3/4 of a turn to the
required tightening torque.
