POWER ASSISTED STEERING PUMP LEVEL
For topping up or filling, use ELF RENAULTMATIC
D2 or MOBIL ATF 220 oil
.
The level, when correct, should be visible between
the

ENGINE AND PERIPHERALS
Oil consumption
10
TESTING METHOD
Oil consumption of 1 litre for 1 000 km (620
miles) is acceptable.
Check there is no external oil leak from the en-
gine.
For accurate testing, certain conditions must be
observed when draining the engine oil :
- the engine should be warm,
- the dipstick and filling plug should be removed.
Drain the engine and leave the oil running out for
15 minutes minimum.
Refit the drain plug and "seal" it (spot of paint co-
vering the plug and the sump) in order to check at
a later date that it has not been removed.
Use a measuring cylinder to check the amount of
oil required to fill the engine:
Engines:
E7J 2.75 litres
K7M 3 litres
F3R 5.5 litres
F8Q 5 litres
Refit the filling plug and seal it.Ask the driver to return the vehicle after 1 000 km
(620 miles) during which time the oil level should
be monitored regularly with the dipstick.
When the vehicle is returned, check the drain and
filling plugs have not been tampered with.
Under the same conditions:
- engine warm,
- dipstick and filling plug removed.
Drain the oil and use a measuring cylinder to
check the amount of oil collected.
Calculate the oil consumption in litres per
1 000 km (620 miles) if the mileage is different.

CHECKING THE GASKET FACE
Use a straight edge and a set of shims to check for
gasket face deformation.
Maximum bow 0.05 mm.
The cylinder head may not be re-ground.
REFITTING (Special notes)
Remove the liner retaining flanges Mot. 588
(except K7M).
Wipe the gasket faces of the cylinder block and
the cylinder head.
Check the centring dowel is present (G).
87474S
Position the cylinder head gasket.
Refit the cylinder head, lubricate the threads and
the bearing faces under the heads of the bolts
with engine oil.
Note : check the length of the bolts for the
cylinder head, the shorter ones are used on the
inlet side.
Cylinder head tightening (see section 07, cylinder
head tightening).
Refitting is the reverse of removal.
For refitting the timing belt, (see section 11-
Timing belt).
Fill and bleed the cooling circuit, (see section 19).

CLEANING
It is very important not to scratch the gasket faces
of parts in aluminium.
Use Décapjoint to dissolve any gasket remaining
on the metal.
Apply the product to the area to be cleaned; wait
approximately ten minutes then remove using a
wooden spatula.
Gloves should be worn during this operation.
Remember that this operation should be carried
out with extreme care to avoid the risk of foreign
bodies being introduced into the oilways bringing
oil under pressure to the camshaft (oilways are
located in both the cylinder head and the cylinder
block).
If this recommendation is not observed there is a
risk that the rocker jets may become blocked and
damage may occur rapidly to the rocker cams and
tappets.
CHECKING THE GASKET FACE
Use a straight edge and a set of shims to check for
gasket face deformation.
Maximum bow 0.05 mm.
The cylinder head may not be re-ground.

Remove clamp Mot. 453-01.
Top up the pump level and run the engine to
check the pressure.
Wheels in straight line:
Regardless of engine speed, the pressure should
not exceed 5 to 7 bars.
Full lock to one side:
Hold the steering at full lock, the maximum
pressure should be 79 to 86 bars.
This operation should not be prolonged to avoid a
high increase in the oil temperature.
Remove union Dir. 803 and pressure gauge
Fre. 1085 or Fre. 244-03 , cutting the supply to the
pump with clamp Mot. 453-01.
Reconnect the high pressure pipe and remove
clamp Mot. 453-01.
