CHECKING THE FUEL SUPPLY PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit (with 0 ;+ 10 bars
pressure gauge included)
Mot. 1311-04 T piece (J union)
Mot. 1311-06 Tool for removing fuel pipes
Disconnect:
- the oil vapour rebreathing pipes and the fuel
vapour recirculation pipes,
99372S
- the fuel supply pipe using small section tool
Mot. 1311-06 (method described in section 13
"Fuel gallery").
99375R
Connect the T piece Mot. 1311-04 to the gallery,
then reconnect the fuel supply pipe to the T piece.

CHECKING THE OIL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 453-01 Hose clamp pliers
Dir. 1204 Pressure test union
Dir. 803 Metric thread union
Fre. 1085
or Pressure gauge
Fre. 244-03
Fre. 284-06 Connecting pipe
Fit clamp Mot. 453-01 to the low pressure pump
hose.
Disconnect the high pressure pipe (take
precautions to catch the oil which will run out).
Insert union Dir. 803 (metric thread) between the
pipe and the pump.
For engines where it is fitted, remove the
pressostat on the rigid pipe (high pressure).
Connect the pressure test union
Dir. 1204 and the oil pressure gauge
Fre. 1085 (or Fre. 244-03 + Fre. 284-06).
77840R1
Connect pressure gauge Fre. 1085 (or Fre. 244-03
+ Fre. 284-06).
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.
Top up the oil in the reservoir.

CHECKS TO BE MADE BEFORE THE ANTI-
POLLUTION TEST
Ensure:
- the ignition system is operating correctly
(correct spark plugs, correctly set plug gap,
high voltage leads in good condition and
correctly connected).
- the injection system is operating correctly
(supply is correct - check using the XR25).
- the exhaust pipe is correct and is sealed.
- the EGR is operating correctly.
Check the vehicle history if possible (run out of
fuel, lack of power, use of incorrect fuel).
CHECKING ANTI-POLLUTION STANDARDS
Run the engine until the engine cooling fan has
operated twice.
Connect a correctly calibrated four gas analyser to
the exhaust tail pipe.
Keep the engine speed at 2500 rpm for
approximately 30 seconds then let the engine
return to idle speed and note the pollutant values.

If, after these tests, the values are correct, the
antipollution system is correct.
If the values are not correct, additional tests must
be carried out:
- Check the condition of the engine (condition
of the oil, valve clearances, timing, etc,...),
- Check the correct operation of the oxygen
sensor (see section 17) ,
- test for the presence of lead (see following
page).
If the test for the presence of lead is positive, en-
sure the vehicle uses two or three full tanks of un-
leaded fuel before replacing the oxygen sensor.
If, after all these tests have been carried out, the
values still do not conform, the catalytic converter
must be replaced. Petrol engine
