Tow Truck TowingNJGI0009S05CAUTION:
All applicable local laws regarding the towing operation
must be obeyed.
It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during towing operation.
Towing is in accordance with Towing Procedure Manual at
dealer.
Always attach safety chains before towing.
When towing, make sure that the transmission, steering
system and power train are in good order. If any unit is
damaged, dollies must be used.
NISSAN recommends that the vehicle be towed with the driving
(front) wheels off the ground as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH
FOUR WHEELS ON GROUND
NJGI0009S0502Observe the following restricted towing speeds and distances.
Speed:
Below 50 km/h (30 MPH)
Distance:
Less than 65 km (40 miles)
CAUTION:
Never tow an automatic transaxle model from the rear (i.e.,
backward) with four wheels on the ground as this may cause
serious and expensive damage to the transaxle.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH
REAR WHEELS RAISED (WITH FRONT WHEELS ON
GROUND)
NJGI0009S0503Never tow an automatic transaxle model with rear wheels raised
(with front wheels on ground) as this may cause serious and
expensive damage to the transaxle. If it is necessary to tow it with
rear wheels raised, always use a towing dolly under the front
wheels.

3. Tighten mounting bolts in two steps in numerical order shown in
figure.
4. Install fuel feed hose.
CAUTION:
Install hose clamp avoiding interference with bulge, and
securely tighten it
5. Install remaining parts in the reverse order of removal.
INSPECTION AFTER INSTALLATION
●Check for fuel leakage with following procedure.
1. Turn ignition switch ON (do not start engine), and check connections for leakage by applying fuel pressure
to fuel piping.
2. Start engine, and re-check connections for fuel leakage by increasing engine speed. 1st step : 11.8 - 13.8 N·m (1.2 - 1.4 kg-m, 9 - 10 ft-lb)
2nd step : 17 - 23 N·m (1.7 - 2.4 kg-m, 13 - 17 ft-lb)

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-34, "
FUEL PRESSURE RELEASE" (WITH EURO-OBD), EC-427,
"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Remove ignition coil and spark plug from each cylinder.
Refer to IGNITION COIL EM-24, "
Removal and Installation" and SPARK PLUG EM-25, "Removal and
Installation" .
4. Connect engine tachometer (not required in use of CONSULT-II).
5. Disconnect fuel injector harness connector so that no fuel is injected.
6. Install compression tester with adapter onto spark plug hole.
●Use compression gauge whose picking up end inserted to spark
plug hole is smaller than 20 mm (0.79 in) in diameter. Otherwise,
it may be caught by cylinder head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.
Compression pressure
[kPa (bar, kg/cm2 , psi)/rpm]
CAUTION:
Always use a fully changed battery to obtain specified engine speed.
●If the engine speed is out of specified range, check battery liquid for proper gravity. Check engine speed
again with normal battery gravity.
●If compression pressure is below minimum value, check valve clearances and parts associated with com-
bustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head gas-
ket). After the checking, measure compression pressure again.
●If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, the piston rings may be worn out or damaged. Check
the piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the 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, the gaskets are leaking. In such a case, replace the cylinder head
gaskets.

1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC-39, “CONSULT-II Inspection
Procedure”.
Do not disconnect CONSULT-II until the end of this operation;
it will be used to check engine rpm and for error detection at
the end of this operation.
4. Disconnect the negative battery terminal.
5. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT2 (20A)] from fuse box on
the left side of engine compartment.
6. Remove glow plugs from all the cylinders.
Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
Carefully remove glow plugs to prevent any damage or
breakage.
Handle with care to avoid applying any shock to glow
plugs.

7. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.
: 18 - 21 N·m (1.8 - 2.2 kg-m, 13 - 15 ft-lb)
8. Connect battery negative terminal.
9. Set the ignition switch to “START” and crank. When gauge
pointer stabilizes, read compression pressure and engine rpm.
Repeat the above steps for each cylinder.
Always use a fully-charged battery to obtain specified
engine speed.

When engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
If engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cylin-
der head gaskets, piston rings, pistons, cylinder bores, cylin-
der block upper and lower surfaces) and measure again.
10. Complete this operation as follows:
a. Turn the ignition switch to “OFF”.
b. Disconnect battery negative terminal.
c. Install glow plugs.
