REPLACING THE OIL FILTER
Remove the oil filter using tool (Mot. 1329).
Coat the sealing ring of the new oil filter with engine
oil.
Tighten the oil filter by hand.

PROCEDURE FOR MEASURING OIL
CONSUMPTION
1 - Filling to the maximum level
Turn the engine off.
Wait 2 minutes for all the oil to flow into the oil sump.
Carry out a visual inspection using the dipstick.
Top up to the "MAX" mark.
Make a paint mark on both the filler plug and the
sump drain plug in order to be able to check later that
it has not been removed.
2 - Customer driving
Ask the customer to drive approximately 1240 miles
(2000 km) in the vehicle without letting the oil level
reach the "MIN" mark.
3 - Topping up
Turn the engine off.
Wait 2 minutes for all the oil to flow into the oil sump.
Carry out a visual inspection using the dipstick.
Top up to the "MAX" mark.
Note the quantity of oil added and the mileage cove-
red since the last top-up to maximum level.
4 - Measurement of the oil consumption
Oil consumption= Quantity of topping up oil (in
litres) / number of kilometres (in thousands).
Note:
The operation should be carried out with the
engine warm after the fan assembly has cut in
once.

I -CHECKING
Ensure that the engine oil level is between the "MIN"
and "MAX" marks.
Use the tool (Mot. 836-05) and a long dowel of 22 mm.
The oil pressure check must be carried out with the en-
gine warm (approximately 80˚C).
II - USE
Connect the pressure gauge in place of the oil pressure
switch.
III - ENGINE MANAGEMENT
K7J/K7M engine:
- Idling : 1 bar
- 3000 rpm: 3 bar
Torque tighten the oil switch (3.5 daNm).
