CHECKING
The oil pressure should be checked when the engine
is warm (approximately 80°C).
USE
Connect the pressure gauge in place of the oil
pressure switch.

In operation, the pressure should stabilise at
210 ± 3.5 mbar.

IMPORTANT: Never attempt to remove the
turbocharger with the engine in place; you will not be
able to follow the recommendations for refitting the oil
supply pipe (1) and the constraints created by blind
tightening the connection (3) will lead to the pipe (1)
rupturing in service.
Fit:
–the pipe (1) to the turbocharger by tightening the
union (3) by hand,
–the turbocharger, by holding the union (4) and
tightening it manually. Tighten the turbocharger
mountings on the manifold to a torque of 2.7 daN.m.
Tighten the unions (4), then (3).
IMPORTANT: It is essential to change the special seal
at the turbocharger oil inlet union (3).
Before running the engine, disconnect the pressure
rail sensor connector (5).
Then run the starter motor until the oil pressure
warning light goes out (persist for a few seconds).
Reconnect the sensor, preheat and start the engine.Run the engine at idling speed and check that there
are no leaks at the oil connections.
Using the fault finding tool, erase the fault as a result
of the sensor being disconnected.
Special precautions
●Ensure that no foreign bodies enter the turbine or
compressor during the refitting operation.
●If there has been a fault in the turbocharger, check
that the air-air exchanger is not full of oil.
If the air-air exchanger is full of oil, it must be
removed, flushed with a cleaning agent and then
left to drain properly.
●Check that the turbocharger oil return pipe is not
partially or completely blocked by scale. Check
also that it is perfectly tight. If not, replace it.

REMOVAL
Put the vehicle on a two post lift.
Disconnect the battery.
Remove:
–the lower engine cover,
–the air exchanger/damper unit pipe after
disconnecting the electrics.
Place hose pliers on the oil tank/power assisted
steering pump return pipe and disconnect the pump.
Separate the power steering reservoir without
disconnecting the pump and move it on the side
member.Remove:
–the turbocharger/exchanger air pipe mounting bolts
from the cylinder head,
–the stiffening bracket (1) between the damper unit
and the power assisted steering pump mounting,
–the exhaust gas recirculation pipe (2) and the seals.
Plan for the replacement of the pipe and the seals
when refitting.
Disconnect the exhaust gas recirculation control
solenoid valve connector.

REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery.
Bleed the engine cooling circuit and engine oil; do not
refit the oil drain plug.
Remove:
–the front right wheel,
–the right-hand wheel arch cover.
Remove the four mounting bolts of the coolant pump
cover.
Lock the crankshaft using a screwdriver in the starter
crown.
Remove the 30 hub lock nut from the coolant pump.Remove the coolant pump sprocket using the
U 14 L FACOM hub extractor
REFITTING
Replace the coolant pump.
WARNING: the rest of the coolant will drop into the
engine housing.
Ensure that the mating surface on the pump is clean
and that the coolant escapes from the engine housing
(oil change).
Refitting is the reverse of removal.

OIL CAPACITY :
–Maximum: 2.8 l
–Minimum: 2.3 l
OIL LEVEL
The oil level is adjusted using a locally manufactured
dipstick, inserting into the oil filler hole (2) (see
Technical Note 2579A).
To check the level it is necessary to remove the left
hand front wheel and the left hand wheel arch cover.
The oil can also be changed and refilled with the
recommended quantity.
1 Drain plug
2 Fuel filler cap
WARNING: the fuel filler cap (2) should not be used to
check the level by overfilling; using too much oil may
damage the seals and overheat the oil. Marks to graduate:
–B: 22 ± 0.5 mm
–C: 30 ± 0.5 mm
