PRECAUTIONS
SPECIAL FEATURES
CAUTION:
 The engine must not operate with:
- Diesel engine fuel containing more than 10% diester,
- Petrol, even in tiny quantities.
 The system can inject the diesel into the engine at a pressure up to 1400 bars. Before carrying out
any work, check that the injector rail is not under pressure and that the fuel temperature is not too
high.
 You must respect the cleaning and safety advice specified in this document for any work on the high
pressure injection system.
 Removal of the interior of the pump and injectors is prohibited. Only the flow actuator, the fuel tem-
perature sensor and the venturi can be replaced.
 For safety reasons, it is strictly forbidden to slacken a injection tube union when the engine is run-
ning.
 It is not possible to remove the pressure sensor from the fuel rail because this may cause circuit
contamination malfunctions. If the pressure sensor fails, the pressure sensor, the rail and the five
injection tubes must be replaced.
 It is strictly forbidden to remove any high pressure supply pump pulley marked number 070 575. If
the pump is being replaced, the pulley must be replaced.
 It is forbidden to repair the wiring connecting the knock sensor (accelerometer) and the CKP sensor
(engine speed sensor). If the wiring should fail, it has to be replaced with new wiring.
 Applying 12 volts directly to any component in the system is prohibited.
 Ultrasonic carbon removal and cleaning are prohibited.
 Never start the engine without the battery being connected correctly.
 It is essential to replace all the disconnected air inlet plastic pipes.
INSTRUCTIONS FOR INJECTION TUBES
CAUTION:
All the injection tube removed must be systematically replaced along with the clips.
TIGHTENING THE INJECTION TUBES
NOTE:
fit the pump/rail pipe before the rail/injector pipes.
Rail-pump pipe
 Undo the rail,
 Grease the threads of the injection tube nuts,
 Insert the injection tube olive into the taper of the high pressure pump outlet,
 Insert the injection tube olive into the taper of the high pressure rail inlet.
 Move the nut into position by hand, on the rail side then the pump side,
 Tighten the rail,
 Tighten the injection tube nuts on the rail side then on the pump side.
Rail/injector pipes
 Undo the rail,
 Grease the threads of the injection tube nuts,
 Insert the injection tube olive into the taper of the high pressure injector inlet,
 Insert the injection tube olive into the taper of the high pressure rail outlet,
 Move the nuts into position by hand, on the injector side then the rail side,
 Tighten the rail,
 Ensure that the new clip, supplied with the new injection tube, is fitted,
 Tighten the nuts of the injection tubes on the injector side first and then on the fuel rail side.
NOTE:
Before fitting a new injection tube, move back the nuts on the pipe then lightly lubricate the nut
threads with the oil from the sachet provided in the parts kit.
CHECKING SEALING AFTER REPAIR
CAUTION:
After any operation, check that there are no diesel leaks.
 Reprime the circuit using the priming pump.
 Start the engine and allow to warm up at idle speed, visually inspecting for any fuel leaks.
 Apply tracing fluid around the high pressure connections of the pipe that has been replaced.
 Once the engine coolant temperature is above 50°C and provided there are no malfunctions present, carry
out a road test, taking the engine speed up to 4000 rpm at least once to check that there are no leaks.
 Perform a visual inspection after the road test to make sure that there are no high pressure leaks.
 Clean off the tracing fluid.

InspectionINFOID:0000000001381466
1. Warm up engine thoroughly. Then stop.
2. Remove glow plug.
3. Disconnect high-pressure supply pump harness connector to avoid fuel injection during measurement.
4. Connect compression gauge attachment hose [SST:
KV113B0400 (Mot. 1592)] (A) to the hole for glow plug.
5. Connect compression gauge (B) to attachment hose (A).
6. Turn ignition switch to START for cranking and check compres-
sion gauge.
7. Perform the same procedure for the other cylinders.
 If compression pressure is below minimum value, check valve
clearances and parts associated with combustion chamber (valve, valve seat, piston, piston ring, cylin-
der bore, cylinder head, cylinder head gasket). After checking, measure compression pressure again.
 If any cylinder has low compression pressure, pour a small amount of engine oil into the glow plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
 If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gaskets are leaking. In this case, replace cylinder
head gaskets.
8. Disconnect compression gauge (B) and attachment hose (A).
9. After inspection is completed, install removed parts.
10. Start the engine, and make sure that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-1043, "
BASIC INSPECTION : Descrip-
tion". Compres-
sion pres-
sure: Refer to EM-333,
"GeneralSpecification".

 Use hand tools, power tools (disassembly only) and recommended
special tools where specified for safe and efficient service repairs.
 When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
 Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precaution for Three Way CatalystINFOID:0000000001606119
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
 Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
 When checking for ignition spark or measuring engine compression, make tests quickly and only when nec-
essary.
 Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the
catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precaution for Fuel (Unleaded Regular Gasoline Recommended)INFOID:0000000001606120
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.

Checking System for Leaks Using the Fluorescent Leak DetectorINFOID:0000000001396445
1. Check A/C system for leaks using the UV lamp and safety goggles J-42220 in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner J-43872 to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and oils, may falsely trigger the leak detector. Make sure the surfaces to be checked are
clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye InjectionINFOID:0000000001396446
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.45 bar, 3.52 kg/cm
2, 50
psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool J-41459.
3. Connect the injector tool to the A/C low-pressure side service fitting.
4. Start engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye
through the low-pressure service valve using dye injector tool J-41459 (refer to the manufacture’s operat-
ing instructions).
6. With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leak size, operating conditions and location of the leak, it may take from minutes to days for the dye to
penetrate a leak and become visible.
